4. Overview of the Instrument
4.2 Glossary
The Stand
Four basic versions of the Leica DMI stand (DMI
3000 B, DMI 4000 B, DMI 5000 B, DMI 6000 B) are
available which can be combined into a wide
range of microscope variants.
The basic building blocks of the Leica
DMI6000 B stand are:
The individual variants and their components,
differences, and applications are described in
this manual. The function and performance of all
microscopy techniques and required accessories of the Leica DMI6000 B will be described in
detail in the section of this manual that covers
the operation of the microscope.
Tube
The tube and tube lens create the primary image
together with the objective.
The tubes are an integral part of the stand and
consist of a basic body and a binocular section.
The trinocular tube also features a photo/video
port. A switchable mirror diverts either 100% of
the light to the eyepieces or camera port, or
splits it, with 50% each going to the eyepieces
and camera port.
A Bertrand lens is also available as an option.
Eyepieces
The eyepieces create an enlarged, virtual image
of the actual intermediate image created by the
objective. The eyepiece serves as a magnifier in
this respect.
Intensity Controller
The stand contains a 12V 100 W transformer for
continuous regulation of the intensity via the intensity controller.
The intensity can be adjusted using the controls
(1.6).
Focus Wheel
The focus wheel allows quick, precise focusing
of the microscopic image. Focusing is realized
by the vertical travel of the objective turret, with
a total range of 9mm.
Incident Light-Fluorescence Unit
The stand features an integrated fluorescence
axis and a motorized filter cube changer with
6 positions.
Aperture Ddiaphragm
The aperture diaphragm determines the resolution, depth of field, and contrast of the microscopic image. The best resolution is obtained
when the apertures of the objective and the
condenser are roughly the same.
The aperture diaphragm in the illuminationlight path is not for setting the image brightness. This should be done only with the intensity controls or neutral filters.
Caution:
16
4. Overview of the Instrument
Condenser
The condenser is a lens system that gathers
light and projects it onto the specimen from
above. The condenser is designed for the utilization of the numerical aperture in the objective.
Condenser Height Adjustment
The markings of the transmitted-light column indicate the height to be set for the used condenser.
Stages and Accessories
The stage is designed to accommodate the
specimens to be observed. Mechanical and motorized 3-plate cross-stages are available for the
Leica DMI 6000 B.
Motorized Objective Turret and Objectives
The motorized objective turret is designed to accommodate the objectives. The L-objectives
with their long working distances especially
take into consideration the correction of varying
container bottom thicknesses.
All microscope objectives are usable, from
1.25:1 to 100 : 1 magnification. All objectives in
the Leica product range with a 25mm thread and
coverslip correction are compatible. For performance data on Leica objectives, please refer to
the most current valid objective lists available
from your Leica representative.
Transmitted Light Illumination Unit
The transmitted light illumination unit consists of
an illumination carrier and the transmitted light
illumination column. The transmitted light illumination carrier does not contain a lamp housing,
but a filter module for two swing-in filters and,
depending on the condenser used, a field diaphragm.
Filter
The filters are generally used to enhance the
contrast of the specimen and are installed in the
illumination carrier. A selection of various filters
can be interchanged as required.
Field Diaphragm
The field diaphragm is used to realize Koehler illumination.
Lamp Housing for Transmitted Light
The lamp housings 107/2 and 107 (both for 12V
100W halogen) are available for the Leica DMI
6000 B. For their descriptions and applications,
please refer to the section of this manual describing the use of the microscope.
The letter L indicates a lamp housing designed
for left-handed operation.
Lamp Housing for Incident Light
The 106 z L lamp housing (for halogen or xenon)
is available for the Leica DMI 6000 B. For their
descriptions and applications, please refer to
the section of this manual describing the use of
the microscope.
The letter L indicates a lamp housing designed

28
Fig. 16 3-plate micromanipulation stage
6. Assembly
The assembly of these stages is identical. The
stages are solidly attached to the microscope by
three screws. In the case of fixed stages, an attachable mechanical stage may be installed
(Fig. 18). These are supplied in a separate package.
Multiple-plate stages are supplied separately.
Like the fixed stages, these stages are mounted
as follows:
• If the screws for the stage are already in the
stand, remove them first. In most cases, the
screws will be found in the packing material
of the stand.
Caution!
!
The screw lengths may vary. When using
screws of different lengths, use the shorter of
the three screws in the front hole and the
equally long ones in the rear holes.
• Use a clean cloth to remove dust and packing
material residue from the stand’s contact
surface with the stage.
• Align the stage so that the pair of holes faces
back toward the illumination axis and the
single hole faces forward toward the tube.
• Align the mounting holes in the stage with the
holes in the support surface. If the holes are
covered, in the case of 3-plate cross-stages
or scanning stages, please shift the upper
stage plate until the opening becomes visible.
• First, tighten the single front screw with the
included 3mm hex screwdriver. Be sure to use
shortest of the three screws in the front
the
hole, as an excessively long screw can
interfere with the focus travel. (If you have a
rotating stage, please continue reading under
"Rotating Stage and Insert Frame for Coverslips").
• Finally, give the front screw a final firm
tightening.
Fixed Stage
Attachable mechanical stages that are designed
to accept a variety of culture dishes are also
available for fixed stages. These mechanical
stages may be attached to either side of the
fixed stage (Fig. 17).
Two screws are located at the underside (right
or left) of the attachable mechanical stage.
Tighten these screws in the threaded holes on
the underside of the fixed stage with the 3mm
hex screwdriver. Retighten these screws from
time to time after frequent use.
The attachable mechanical stage has been preadjusted in the factory. In the event that the attachable mechanical stage runs out of focus
when moving from right to left, this can be corrected by Leica’s technical service.
Next, remove one or more of the ordered insert
frames (Fig. 20) from their packaging and place
the insert frame into the precise retention system. The stage, the attachable mechanical
stage, and the insert frame are now ready for
use.
Some (not all) inserts are provided with self-adhesive scales to allow the coordinates to be
read.
Apply these scales to the recesses of the attachable mechanical stage.

place on the box is called "XY Stage".
Scanning stage: After installing the stage, connect the included stage cable first to the X and Y
sockets of the stage and the DM STC control
unit for the scanning stage: XY Stage
Next, connect the DM STC control unit to the
CRT6000 box. Connect the Y-cable as follows: Insert the small round plug into the COAX CTRL
socket and the second flat plug in the XYZ-Con-trol socket of the CRT6000 box. Connect the plug
with the two cables to the SmartMove.
A variety of inserts (including heating ones) are
available for the normal 3-plate and scanning stages. Install these inserts diagonally from above into
the corner with the spring clips. The insert will
click into place when installed properly.
Caution:
!
Press the spring clip into place only from the
side.
Do not press the insert onto the spring clips diagonally from above, as the insert will not be
aligned parallel to the stage and may be bent in
the process.

6. Assembly
Rotating Stage and Insert Frames for Coverslips
The rotating stage (Fig. 30) is also mounted with
3 screws (30.2). Rotate the stage to make all of
the threaded holes accessible. Insert the
screws (30.2).
Caution:
!
Use additional washers (30.3) for the rear holes.
Tighten the screws only lightly, as the rotating
stage must be centered first: Insert the adjusting
aid into the rotating stage for this purpose. Activate the Bertrand lens and focus, or use a focusing telescope (Fig. 32). Move the stage until
the bright circle is in the middle of the field of
view. Next, tighten the stage, swing the Bertrand lens out and remove the adjusting aid.
To insert glass slides in insert frames (31.1),
press on the center of the leaf spring (31.2) and
insert the coverslip in the direction of the arrow.
Clamp the insert frame in the attachable mechanical stage (30.1).

6. Assembly
All the Leica DMI 6000 B microscope condensers feature 7-position turrets and can be
equipped individually with suitable ring diaphragms for phase contrast (PH), darkfield (DF)
or IC prisms for DL interference contrast (DIC).
Light rings and condenser prisms are generally
already installed in the turret at the factory,
making the following assembly steps unnecessary. Please continue on →
page 37, Installation
of Condensers.
To change the components, proceed as follows:
Installing the Light Rings
Change the light rings only with the instrument’s
power turned off. To change the light rings, start
by removing the complete condenser from the
transmitted light illumination axis. Simply release the socket-head screw at the right side of
the condenser mount. The condenser can now
be removed very easily with Leica’s own condenser quick release. Open the condenser cov-
er at the top right side. You will now have access
to the various numbered openings for the light
rings.
Install light rings for phase contrast (designated
by the ID numbers 0, 1, 2, 3 and the focal intercept S of the corresponding condenser head)
and the DF diaphragm (designated by D for darkfield and the focal intercept S of the corresponding condenser head) in the positions of the turret
disk as follows:
Fig. 33 Condenser base S1-S28

Condenser head S28
6. Assembly
• Select a position and make sure that the two
mounting screws have been released to the
point that they no longer extend into the
position. To adjust the screws, turn the
desired light ring position into the beam path.
You can now turn the screws using the two
adjusting keys.
• Next, take the special condenser tool (Fig. 38).
• If possible, install the light rings 0 to 3 in
ascending order. The numbering of the
openings is located at the edge of the crown
gear (4 large openings: 1-4; 3 small openings:
5-7).
• Grasp the light ring to be installed with the
condenser tool (the lettering must face
upward and be legible) so that the groove of
the tool just reaches over the edge of the light
ring and the upper edge of the light ring is
lying flat in the holder of the tool. Press the
cheeks of the tool to grasp the light ring.
• Place the light ring in the desired opening and
make a note of the opening and light ring
designation for the subsequent configuration
of the Leica Application Suite (LAS).
• Insert the light ring at a slight angle from
above so that the frame slides under the spring clip of the receptacle. Do not press the
spring clip down under any circumstances.
This can destroy the clip or result in an
unstable position of the light ring.
• Once the light ring is properly positioned,
release the tool and install the remaining light
rings in the same way.

6. Assembly
Please continue reading if you also have to install IC prisms. Otherwise, skip to the next section.
Installation of IC prisms
The IC prisms are installed at the factory. To
change the components, proceed as follows:
Change the IC prisms only with the instrument’s
power turned off. To change the IC prisms, start
by removing the complete condenser from the
transmitted light illumination axis. Simply release the socket-head screw at the right side of
the condenser mount. The condenser can now
be removed very easily with Leica’s own condenser quick release. Open the condenser cover at the top right side. You will now have access
to the various numbered openings for the IC
prisms.
• IC prisms can only be installed in the large
positions of the condenser turret with guide
grooves.
• Select a position and make sure that the two
mounting screws have been released to the
point that they no longer extend into the
position. It is advisable to remove one of the
screws when installing a prism, as a single
screw is sufficient for centering. The
opposing pressure resulting from the use of
two screws may destroy the prism.
• Next, take the special condenser tool (Fig. 38).
• If possible, install the prisms 0 to 3 in
ascending order. The numbering of the
openings is located at the edge of the crown
gear.
• Grasp the prism to be installed with the
condenser tool (the lettering must face
upward and be legible) so that the groove of
the tool just reaches over the edge of the
prism and the upper edge of the prism is lying
flat in the holder of the tool. The numbers K2
to K16 should be positioned toward the end of
the tool. Press the cheeks of the tool to grasp
the light prism.

6. Assembly
• Place the prism in the desired opening and
make a note of the opening and prism
designation for the subsequent configuration
of the Leica Application Suite (LAS).
• Insert the prism at a slight angle from above
so that the frame slides under the spring clip
of the receptacle. Do not press the spring clip
down under any circumstances. This can
destroy the clip or result in an unstable
position of the prism. Two guide hooks are
located on the underside of the prisms. These
must fit into the two grooves of the opening.
Only one of the two possible alignments is
correct.
• The ID, e.g. K10, must be visible when the
prism is installed and must be oriented toward
the center of the condenser. The prism will
also fit with the ID facing outward, but DIC
imaging will not be possible in this position.
• Use the adjusting key to tighten the centering
screws to the point that they no longer extend
over the edge of the disk. Use only the left
centering screw to position the prism (see ICT
operation). The right centering screw must
not restrict the range of adjustment under any
circumstances.
• Use the front openings to coarsely center the
prisms; the screws must not extend beyond
the outer edge of the disk under any
circumstances.
• Perform the fine adjustment with the Bertrand
lens or telescope after switching the unit on.
Installation of Condensers
The installation procedure is identical for all
condensers S1 to S70 (motorized or manual/coded).
Release the socket-head screw at the right side
of the condenser holder. Place the condenser on
the retaining pins of the illumination arm and
move the condenser to the correct height. Use
the markings on the column and condenser to
determine the correct position.
Once you have reached the correct position,
tighten the socket-head screw.
Fig. 40

• If necessary, carefully remove dust or
fingerprints from the prisms.
• Once the prism is properly positioned, release
the tool and install the remaining prisms in the
same way.

Condenser Heads
Four different condenser heads are available:
1)S1/1.40 oil
2)S1/0.90 dry
3)S23/0.53
4)S28/0.55
Condensers 3 and 4 are screwed directly into
the condenser body. A spacer ring (42.2) must
be screwed into the thread at the bottom of the
condenser body prior to installing condensers 1
and 2. The S1 condenser heads will fit into this
ring.
The S70 condenser is delivered complete with a
condenser head, which makes additional assembly unnecessary.

7.1 Functional Principle
Because of its intelligent automation, the Leica DMI6000 B can be controlled using a variety of control elements.
1. Intelligent Automation
• Switching between contrast methods at the touch of a button. Light rings, DIC prisms, etc.
are automatically positioned in the beam path.
• The microscope recognizes the selected objective and associated contrast method.
The intensity (INT), aperture diaphragm (AP), and field diaphragm (FD) are always set to
suitable values.
• The INT, AP, and FD values are always based on the currently activated illumination axis
(transmitted light or incident light).
• The INT, AP, and FD values can be adjusted individually. Manual adjustments overwrite the
previous settings. The current setting is stored and is retained from one session to the next
when power is switched off.
2. Controls
• SmartMove knobs
for stage and focus control.
• Fixed function buttons on stand
for INT, AP, and FD, as well as for switching between transmitted light and incident light
axis.
•Variable function buttons on stand and SmartMove
These function buttons have functions suitable to the configuration of your microscope assigned to them at the factory. The functions can be reprogrammed and/or adapted to your
specific requirements, however.

7.6.1 Transmitted Light
If your microscope has not yet been set up for
Koehler illumination, please continue with the
"Koehler Illumination" section.
• Select an objective with moderate
magnification (10x-20x).
• Activate the transmitted light axis with the TL/IL button (84.1).
• Press the BF button to activate the brightfield
contrast method (one of the variable function
buttons on the stand).
• Place a specimen on the stage.
• Focus the specimen using the SmartMove or
the focus wheels.
• Adjust the light intensity with the INT buttons
(84.3).
• Close the field diaphragm with the FD button
(84.4) or manually until the edge of the
diaphragm appears in the field of view.
• Using the condenser height adjuster (90.2),
adjust the condenser until the edge of the
field diaphragm appears in sharp relief.
• Open the field diaphragm just enough for it to
disappear from the field of view (91d).
The condenser height setting is dependent on
the thickness of the specimen and may require
adjustment for each new specimen.
Koehler Illumination
Suitable aperture and field diaphragm values
have been preset for each objective. The condenser has also been centered at the factory.
However, it may be necessary to readjust the
condenser in some cases. Therefore, check the
condenser centering.
The following procedure is provided for the
transmitted light-brightfield illumination.
All required functions can be executed at the
touch of a button with the Leica DMI 6000 B
electronic microscope. (See Chapter 8, Operation).
Preparation:
• Configure the microscope as follows:
Set up the illumination, condenser, objectives
and eyepieces correctly. (Please make sure
that the objectives are properly screwed in
and check the eyepiece settings.)
• Switch the microscope on and wait for the
initialization phase to complete (automatic
functions only).
•You will need either an empty Petri dish
(preferably with a glass bottom) with a
marking in the middle or a stained specimen
on a slide with a coverslip.
• Switch to the 10x objective (if not present, the
20x objective).
Note:
65
7. Start-up
• Make sure that the condenser is at the
correct height. The condenser height
adjustmentlets you set the condenser head to
the height of the nominal free working
distance. (For an S23 condenser, for example,
the distance between the surface of the stage
and the front lens of the condenser is approx.
23mm).
• Hold a piece of white paper (approx. 3-10cm)
under the light source (field diaphragm).
A light ring should appear on the paper – if
not, check the power cable, the light source
and the fuse of the supply unit (CTR box) and
make sure that all of the parts are correctly
connected to one another.
• Open the field diaphragm as far as possible
until the light ring reaches its maximum
diameter.
• Next, hold the paper under the condenser,
directly on the stage. Open the aperture
diaphragm as far as possible, until the light
ring has reached its maximum brightness. In
order to achieve maximum brightness, make
sure that no port is activated. The full light
should be directed to the VIS port.
• Check the magnification changer to make
sure that the 1x tube lens is selected.
• Adjust the lenses of the eyepieces so that
circle is visible in the eyepieces (not two!). If
you wear eye glasses, remove the antiglare
hoods from the eyepiece tubes (or fold them
back).
• Make sure that the focus on the eyepieces is
set to ±0 (turn the upper part of the eyepiece
tubes until the silver ring is just covered).
•You should see light when looking through the
eyepieces at this point.
If the light is too bright, reduce it as required.
Remove all unneeded components from the light
path.
one
• Swing all filters (in the filter magazine of the
lamp housing or the filter holder of the
condenser) out of the beam path.
• Set the condenser disk to the brightfield
position.
• If your microscope is equipped for DIC:
• Remove the polarizer.
• Remove the analyzer.
• Remove the objective prism (move the
magazine to the "empty" or "brightfield"
position).
• If your microscope is equipped for
fluorescence:
• Select an empty filter position (or a filter
with low transmission in the visible range,
e.g. filter A).
Now to begin with the actual Koehler illumination:
• Place your specimen on the stage and focus
so that you can see its details as clearly as
possible. You probably will not get a perfect
image at this point, as the illumination will not
be optimal (90a).
• Next, attempt to get a sharp image (or at least
a part of the image at the edge) by carefully
the condenser up and down (90.2). Try
moving
this with a variety of field diaphragm settings
until you get a clear, sharp image (91.b). This
may take a while!
•To center the sharp image, insert the
centering keys in the openings provided at
either side of the top part of the condenser
(90.1). Move the image into the center of the
field of view (91.c). Next, open the field
diaphragm until the image fills nearly the
entire field of view. The black edges of the
image should have the same distance to the
outer edge of the field of view on all sides. If
66
7. Start-up
not, recenter the image with the centering
screws. Adjust the height of the condenser
until the edges are sharp. Now open the field
diaphragm until the image fills the entire field
of view and the black edges have disappeared
completely (91.d).
• The last step is the adaptation of the contrastsettings. To improve the contrast, close the
aperture diaphragm – if you close it too far,
however, the resolution of the image details
will deteriorate.
To see the aperture diaphragm, remove an
eyepiece tube and look directly into the tube.
Your eye should be around 10 to 20 cm from
the tube. Change the size of the aperture
diaphragm until its image is clearly visible in
the pupil of the objective.
• Set the aperture diaphragm to cover 2/3 to 4/5
of the pupil diameter. You will now have the
optimal balance between resolution and
contrast.

7.6.2 Incident Light - Fluorescence
Suitable aperture and field diaphragm values
have been preset for each objective. The incident light module has also been centered at the
factory.
However, it may be necessary to readjust the incident light module in some cases after transporting and setting up the stand. Therefore,
check the field diaphragm centering.
The following procedure is provided for the incident light-brightfield illumination.
• Select an objective with moderate
magnification (10x-20x).
• Activate the incident light axis with the TL/IL
button (84.1).
• Press the IL-BF / Fluo button to activate the
brightfield contrast method (one of the variable function buttons on the stand).
• Place a specimen on the stage.
Adjusting the Field Diaphragm
• Close the field diaphragm with the FD button
(84.4) or manually until the edge of the
diaphragm (round or rectangular) appears in
the field of view.
• If the limits of the field diaphragm are not in
the center of the field of view, move the
position of the field diaphragm to the center
with the two centering screws (92.1) on the
right side of the stand.
• Use the function buttons FD (84.4) to open the
field diaphragm to the point that they just
disappear from the field of view.
•We recommend the use of a rectangular field
diaphragm when using a digital camera.
Match the size of the diaphragm to the chip
size of the camera.
• Focus the specimen using the SmartMove or
the focus wheels.
• Adjust the light intensity with the INT buttons
(84.3).

7.7 Checking Phase Contrast Rings
If your microscope is equipped for phase contrast, light rings to match your objectives will be
installed in the condenser.
The light rings are already centered in the factory. However, the centering should be rechecked.
Note:
Each objective has its own light ring assigned to
it in the condenser. The test must therefore be
performed for each objective. When selecting
an objective suitable for phase contrast, the appropriate light ring will automatically be selected as well.
• Press the BF (brightfield) button (one of the
variable function buttons on the stand).
• Instead of an eyepiece, place a focusing
telescope (Fig. 93) in the observation tube or
activate the Bertrand lens (pull rod (94.1) on
tube).
• Select the phase contrast objective with the
lowest magnification (one of the variable
function buttons on the SmartMove).
• Focus on the specimen using the SmartMove
or the focus wheels.

• Retighten the clamping ring.
• Press the PH (phase contrast) button (one of
the variable function buttons behind the focus
wheels). The light ring will be selected in the
condenser.
• If the light ring and the phase ring are not
shown as arranged in Fig. 95c, the light ring
must be centered.
• Insert the centering keys into the openings
provided on both sides of the condenser
(90.3).
•Turn the centering keys until the dark ring
(phase ring in the objective) is congruent with
the slightly narrower bright ring (light ring in
condenser) (95 c).
7.8 Setting the Motorized Polarizer
• Select the POL method (one of the variable
function buttons on the stand).
• Insert the centering key in the opening
provided on the condenser (Fig. 96).
• Set up optimal darkening. (The analyzer must
be in place.)
• Remove the centering keys.

Mercury Lamps
• The adjustment window shows the direct
image of the arc and its mirror image. These
are generally not in alignment with one
another.
Caution!
Light sources pose a potential irradiation
risk (glare, UV-radiation, IR-radiation).
In the lamp housing 106 z, the direct image of the
filament (in halogen lamps) or the arc (in gas discharge lamps) and its reflection are focused separately and adjusted in relation to one another.
An adjustment window (2.8, p. 19) in which the
light source is visible is located on the right side
of the microscope.
Adjust the lamp as follows while observing the
light source in the adjustment window.
• Focus the direct image with the collector
(100.6).
• Use the adjusting buttons to pivot the arc’s
mirror image on the rear side of the lamp
housing (100.2,100.4) to the side or completely
out of the beam path. The arc’s focused
image remains visible (Fig. 101).
• Use the adjusting buttons (100.1 and 100.5) to
place the direct arc image in the middle of the
centering plane, whereby the bright tip of the
arc, the focal spot, should lie slightly outside
the center (Fig. 102).
• Then pivot the arc’s mirror image with the
adjusting knobs (100.2) and (100.4) and focus it
using the reflector (100.3).
• Use the adjusting knobs (100.2) and (100.4) to
orient the mirror image symmetrically to the
direct image (Fig. 103).
The V-shaped irradiation of the direct image
and mirror image arcs can be superimposed.
Caution!
The bright tips of the arcs, the focal spots,
must never be projected onto each other, as
this results in a danger of explosion by overheating.
Caution!
The structure of the arc can no longer be
made out clearly in lamps that have been in
service for a long time. The image and mirror
image can no longer be superimposed exactly. In this case, align both images.

• Using the collector, defocus the image with
the knob (100.6) until the arc image and mirror
image are no longer recognizable and the
image is homogeneously illuminated.
• Replace the lamp adjustment reflector with
the original filter cube.

Note:
The eyepiece’s aperture protector must be removed or folded back, during microscopy while
wearing eyeglasses.
We recommend removing bifocals and
spectacles with progressive-addition lenses
when using the microscope.
8. Operation
We recommend running a teach-in via the Leica
Application Suite (LAS) software when using
eyepieces not included in the scope of delivery.
This will ensure that the total magnification
shown in the LeicaScreen is correct.
8.8 Objectives
Changing Objectives
• For the adjustable tubes with documentation
output, choose the 100% VIS position.
Eyepieces with Inlaid Reticle
• Focus the reticle by adjusting the eyelens.
• Focus on the object through this eyepiece.
• Then, close that eye and focus on the object
by adjusting only the second ocular.
Correction for Vision Problems
• With your right eye, look through the right
eyepiece and bring the specimen into sharp
focus.
• Then, with your left eye, view the same
specimen and rotate the left eyepiece tube
until the object is brought into sharp focus.
Do not change the Z position in the process!
The objectives can be selected with the function
buttons on the stand or the SmartMove, or by
manually turning the objective turret. When
changing objectives manually, please make sure
that the turret clicks into position.
The positions of the objectives in the objective
turret have been specified at the factory and
must be observed when installing the objectives.
(→ also see Objectives, p. 39).
When selecting an objective, the microscope
automatically selects:
• The optimal setting for the field diaphragm
• The optimal setting for the aperture
diaphragm
• The light intensity for the current contrast
method
The objective magnification and total magnification are displayed on the LeicaScreen.
Note:
• For immersion objectives use the appropriate
immersion medium.

2) Immersion objectives (IMM)
• First, select the operating mode (Imm or Dry)
using the function buttons.
The operating mode may also be selected in
the Leica Application Suite (LAS).
• The objective turret is lowered to its bottom
stop. This is to permit the application of the
immersion liquid when changing from a dry to
an immersion objective. It also permits the
removal of the liquid when changing to dry
mode.
The current objective remains in the beam
path.
• Next, press the button for the objective you
intend to use.
Note:
If the Imm or Dry operating mode buttons are
pressed accidentally, the original mode can be

When replacing objectives, you must perform a
teach-in for the new objectives in the Leica Application Suite (LAS). A parfocality teach-in
should also be performed.
Color Coding of Objectives
The magnification of each objective is indicated by a color ring in accordance with DIN/ISO standards:
For lockable immersion objectives lock these by
pushing the front part upwards until it stops (approx. 2mm). Then, after a gentle turning motion
to the right, the objective is locked.
For objectives with corrective mounts turn the
knurl to adjust the objective to the thickness of
the cover glass.

10.2 Cleaning
Caution!
10. Care of the Microscope
Unplug the power supply before performing
cleaning and maintenance work!
Protect electrical components from moisture!
Microscopes in warm and warm-damp climatic
zones require special care in order to prevent
fungus contamination.
The microscope should be cleaned after each
use, and the microscope optics should be kept
strictly clean.
10.1 Dust Cover
Note:
To protect against dust, cover the microscope
and accessories with the dust cover after each
use.
Caution!
Let lamps cool down before covering the
stand with a dust cover. The dust cover is
not heat-resistant. In addition condensation
water may occur.
Caution:
!
Residual fiber and dust can create unwanted
background fluorescence.
Cleaning Coated Parts
Dust and loose dirt particles can be removed
with a soft brush or lint-free cotton cloth.
Stubborn dirt can be removed with all commonly
available aqueous solutions, naphtha or alcohol.
For cleaning coated parts, use a linen or leather
cloth that is moistened with one of these substances.
Caution:
!
Acetone, xylene or nitro-containing thinner
can harm the microscope and thus must not
be used.
Test cleaning solutions of unknown composition
first on a less visible area of the unit. Be sure
that coated or plastic surfaces do not become
matted or etched.
Cleaning the Stage
Rub the stage with paraffin oil or acid-free Vaseline to remove light spots on the stage.
95
10. Care of the Microscope
Cleaning Glass Surfaces
Remove dust on glass surfaces with a fine, dry,
and fat-free hair brush, by blowing with a blow
bag or vacuum suction.
Remove stubborn dirt on glass surfaces with a
clean cloth dampened with distilled water. If the
dirt still can not be removed, use pure alcohol,
chloroform or benzine.
Cleaning Objectives
Caution!
The objective may not be unscrewed during
cleaning. If damage appears on inner surfaces, the objectives must be sent to your
Leica subsidiary for repair. We also advise
against cleaning the inside surfaces of the
eyepieces.
The front lenses of objectives are cleaned as
described under "Cleaning Glass Surfaces". The
upper lens is cleaned by being blown off with a
pneumatic pump.
Removing Immersion Oil
Caution!
Follow safety instructions for immersion oil!
First, wipe off the immersion oil with a clean
cotton cloth, and then re-wipe the surface several times with ethyl alcohol.
10.3 Handling Acids and Bases
For examinations using acids or other aggressive chemicals, particular caution must be taken.
Caution:
!
Be absolutely certain to prevent the optics
and mechanical parts from coming into contact with these chemicals.
