2. Intended Purpose of the Microscope

2. Intended Purpose of the Microscope

The Leica DMI Series microscopes covered in
this manual are designed for biological, routine,
and research applications. This includes the ex­amination of samples taken from the human body
in order to provide information on physiological
or pathological states or congenital abnormali­ties; to determine the safety and compatibility
with potential recipients; or to monitor therapeu­tic measures.

The Leica DMI Series is an additional develop­ment of Leica’s proven inverted research mi­croscopes, designed for cellular and tissue
examination, micromanipulation and microinjec­tion techniques, microdissection, and confocal
microscopy. The Leica DMI Series is suitable
for universal deployment. All contrast methods
such as dark fi eld, bright fi eld, phase contrast,
DIC, fl uorescence, and modulation contrast are
integral to the microscope and can be adapted
or changed quickly and easily. Variable illumi­nation and imaging beam paths, as well as HCS
optics, modular accessories, and a comprehen­sive range of peripherals complement the Leica
Microsystems inverted research stand.

The above-named microscope series complies
with the Council Directive 98/79/EEC concern­ing in vitro diagnostics. They also conform to the
Council Directives 73/23/EEC concerning electri­cal apparatus and 89/336 /EEC concerning elec­tromagnetic compatibility for use in an industrial
environment.

Caution!

The manufacturer assumes no liability for
damage caused by, or any risks arising from,
using the microscopes for purposes other
than those for which they are intended or not
using them within the specifi cations of Leica
Microsystems CMS GmbH.
In such cases the declaration of conformity
shall cease to be valid.

Caution!

These (IVD) devices are not intended for use
in the patient environment defi ned by DIN
VDE 0100-710. Neither are they intended for
combining with medical instruments accord­ing to EN 60601-1. If a microscope is electri­cally connected to a medical instrument
according to EN 60601-1, the requirements
defi ned in EN 60601-1-1 shall apply.

3. Safety Notes

Caution!

Power plugs may only be plugged into an out­let equipped with a grounding contact.

Do not interfere with the grounding function
by using an extension cord without a ground
wire. Any interruption of the ground wire in­side or outside of the device, or release of
the ground wire connection, can cause the
device to become hazardous. Intentional
ground interruption is not permitted!

Caution!

Peripheral devices with their own or sepa­rate power supplies that are connected to
the microscope can have the same protec­tive conductor potential by connecting them
to the ground screw on the back of the Leica
CTR4000, CTR6000, CTR6500 and CTR7000
electronics boxes. For connections without
a ground connector, Leica Service must be
consulted.

Caution!

The microscope’s electrical accessory com­ponents are not protected against water. Wa­ter can cause electric shock.

Caution!

Protect the microscope from excessive tem­perature fl uctuations. Such fl uctuations can
lead to the accumulation of condensation,
which can damage the electrical and optical
components.
Ambient temperature: 15–35°C.

Caution!

Before exchanging the fuses or lamps, be ab­solutely certain to switch off the main power
switch and remove the power cable.

Caution!

Never use any fuses as replacements other
than those of the types and the current rat­ings listed here. Using patched fuses or
bridging the fuse holder is not permitted. The
use of incorrect fuses may result in a fi re haz­ard.

3. Safety Notes

3.3 Safety Instructions
for Handling the Light Sources

Caution!

Light sources pose a potential irradiation risk
(glare, UV-radiation, IR-radiation). Therefore,
lamps have to be operated in closed hous­ings.
Never look directly into the beam path (blind­ing hazard).

Connect the light guide to the microscope
fi rst to prevent exposing the user to the high­energy light output of the Leica EL6000 com­pact light source.
Never look directly into the light emitted by
the light guide.

3.4 Notes on handling laser devices

The microscope is not suitable for coupling laser
devices into the camera ports (refer to Chapter

4), as this creates a danger to the user from laser

radiation.

For use of the microscope with lasers, Leica
Microsystems offers special microscopes with
additional safety devices.

For further information, please contact your au­thorized Leica Microsystems representative.

Caution!

Follow safety instructions for immersion oil!

6.3 Installation of the DIC Module
and DIC Objective Prisms

If your microscope is not equipped with DIC,
please continue with Chapter 6.4.
In the Leica DMI series microscopes, the DIC
prisms are already installed in the DIC disk below
the objective turret (Fig. 10b).

Motorized, manual
coded and manual DIC disks are available. The
installation is identical for all types.

Proceed as follows when making changes to the
IC prism disk:

• Remove the front cover (Fig. 11) below the

objective revolver after releasing the socket
screws (Fig. 10a).

Fig. 10a Removing the front cover

Fig. 11 Front cover, DIC prism disk

• Insert the DIC prism disk (Fig. 10b) squarely in
its receptacle. First, lightly tighten one screw
with the included 3 mm hex screwdriver, then
tighten both Allen screws.

Note: insert the prism disk with the electronics

board facing down. Do not touch the electron­ics (especially the contacts) with your bare fi n­gers!

Replacing Individual IC Prisms:

• Release the two socket screws and remove
the prism disk.

• Place the prism against the stop pin (10b.3),
place the washer between the screw and the
prism, and tighten gently to prevent undue ten­sion. Insert the prism so that its identifying let­ter, e.g. ID, is facing upward and is legible.

• After installing the prisms, replace the prism
disk in its receptacle.

6.4 Installation of Specimen Stages

A wide range of specimen stages are available.
The most important are the following:

• Fixed stage (248 mm x 204 mm) (Fig. 13):
normal, heating and temperature-controlled,

with and without attachable mechanical stage

• Fixed micromanipulation stage (248 mm x
204/112 mm) (Fig. 15): normal, heating, and
temperature-controlled, with and without at­tachable mechanical stage

• Standard manual (Fig. 14) and motorized
3-plate cross-stage, positioning range: 83 mm
x 127 mm

• Manual (Fig. 15) and motorized micromanipu­lation 3-plate cross-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 fi xed 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 fi xed stages, these stages are mounted
as follows:

• If the screws for the stage are already in the
stand, remove them fi rst. 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 for 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 3 mm hex screwdriver. Be sure to use
the shortest of the three screws in the front
hole, as an excessively long screw can inter­fere with the focus travel.

• Next, fi rmly tighten the two rear screws.

• Finally, give the front screw a fi nal fi rm tighten­ing.

6. Assembly

Fixed Stage

Attachable mechanical stages designed to ac­cept a variety of culture dishes are also available
for fi xed stages (Fig. 18).

Two screws are included with the attachable
mechanical stage. Tighten these screws in the
threaded holes on the underside of the fi xed
stage with the 3 mm 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 self­adhesive scales to permit the coordinates to be
read.

Apply these scales to the recesses of the attach­able mechanical stage.

to specifi c positions at the factory. For details,
check the identifi cation sheet included with your
order.

Now open the drawer several mm further until
it clicks into its end position. Actuate the lever
(66.1) to engage the turret disk in the loading po­sition.

You can now insert a fi lter block. Proceed as fol­lows:

• With the holder facing you squarely, insert

the fi lter or refl ector cubes into the holder in
accordance with the included identifi cation
sheet.

• The fl uorescence cubes are suitable for both

upright and inverted microscopes. When using
them with inverted microscopes, insert them
so that the writing is upside down along the
lower edge.

• Release the lever (66.1) again to turn the disk
on to the next loading position. Continue in this
way for all of the cubes.

• Once all fi lter and refl ector cubes have been
inserted, close the drawer and replace the
analyzer or cap.

6.14 Inserting the Front Module Slider

If your microscope is prepared for integrated
modulation contrast or integrated phase con­trast, a front module (possibly in conjunction with
a manual magnifi cation changer) will be integrat­ed in the stand. This is recognizable by a 2 x 3 cm
opening at the left front side of the microscope.
If this opening is not present or closed, then your
microscope is not prepared for the integrated
processes.
A slider for integrated modulation contrast or in­tegrated phase contrast fi ts in this opening. The
phase contrast slider may still require the instal­lation of phase rings.
Insert the slider with the markings facing for­ward. It features a bright fi eld position and two
positions for contrast methods (position A and
position C).
(A and C designate the eyepoint of the used ob­jective. Please refer to the included objective list
for the eyepoint of your objective. It can also be
found engraved on the objective.)

7.1 Functional Principle (Leica DMI4000 B and Leica DMI6000 B)

Thanks to its intelligent automation, the Leica DMI4000 B and 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 fi eld 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, SmartMove, STP6000

These function buttons have functions suitable to the confi guration of your microscope as-

signed to them at the factory. The functions can be reprogrammed and/or adapted to your
specifi c requirements, however.

• Complete control of microscope and camera via software

(Leica Application Suite (LAS/LAS AF))

60

Note: ( reset function)

The microscope can be reset to its factory de­fault programming:

• With the stand switched off, press the top three
variable function buttons on the left side of the
stand.

• Switch on the power for the stand.

• Hold the buttons until the initialization is com­plete.

• The standard information display will now ap­pear on the LeicaDisplay.

• Switch the instrument off and back on. The set­tings are now saved.

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-bright fi eld illumination.
All required functions can be executed at the
touch of a button with the Leica DMI6000 B elec­tronic microscope. (See Chapter 8, Operation).

• Adjust the light intensity with the INT buttons
(84.3).

• Close the fi eld diaphragm with the FD button
(84.4) or manually until the edge of the dia­phragm appears in the fi eld of view.

• Using the condenser height adjuster (90.2), ad­just the condenser until the edge of the fi eld
diaphragm appears in sharp relief (not S70
condenser).

• Open the fi eld diaphragm just enough for it to
disappear from the fi eld of view (91d).

70

Preparation:

• Confi gure the microscope as follows:
Set up the illumination, condenser, objectives

and eyepieces correctly. (Please ensure 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.

7. Start-up

• Switch to the 10x objective (if not present, the
20x objective).

• Ensure that the condenser is at the correct
height. The condenser height adjustment lets
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. 23 mm).

• Hold a piece of white paper (approx. 3-10
cm) under the light source (fi eld 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
ensure that all of the parts are correctly con­nected to one another.

• Open the fi eld 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, ensure that
no port is activated. The full light should be di­rected to the VIS port.

• Check the magnifi cation changer to ensure
that the 1x tube lens is selected.

• Adjust the lenses of the eyepieces so that one
circle is visible in the eyepieces (not two!). If
you wear spectacles, remove the antiglare
hoods from the eyepiece tubes (or fold them
back).

• Ensure 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.

• Swing all fi lters (in the fi lter magazine of the
lamp housing or the fi lter holder of the con­denser) out of the beam path.

• Set the condenser disk to the bright fi eld posi­tion.

• If your microscope is equipped for DIC:

• Remove the polarizer.

• Remove the analyzer.

• Remove the objective prism (move the mag-

azine to the „empty“ or „bright fi eld“ posi­tion).

• If your microscope is equipped for fl uores­cence:

• Select an empty fi lter position (or a fi lter with

low transmission in the visible range, e.g. fi l­ter 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
moving the condenser up and down (90.2). Try
this with a variety of fi eld 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 fi eld of view (91.c).
Next, open the fi eld dia phragm until the image
fi lls nearly the entire fi eld of view. The black

71

7. Start-up

edges of the image should have the same dis­tance to the outer edge of the fi eld of view on
all sides. If not, recenter the image with the
centering screws. Adjust the height of the con­denser until the edges are sharp. Now open
the fi eld diaphragm until the image fi lls the
entire fi eld of view and the black edges have
disappeared completely (91.d).

• The last step is the adaptation of the contrast
settings. 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

Leica DMI3000 B:

• Select an objective with moderate magnifi ca­tion (10x–20x) and adjust the image.

• Close the fi eld diaphragm with the turning knob
until the edge of the diaphragm (round or an­gled) appears on the specimen level.

• If the limits of the fi eld diaphragm are not in the
center of the fi eld of view, move the position
of the fi eld diaphragm to the center with the
two centering screws on the right side of the
stand using a 3 mm Allen key. When center­ing, observe the position of the fi eld diaphragm
through the eyepieces or on the monitor.

• Open the light fi eld diaphragm until it just dis­appears from the fi eld of view.

7. Start-up

Leica DMI4000 B and Leica DMI6000 B:

Suitable aperture and fi eld diaphragm values have
been preset for each objective. The inci dent light
module has also been centered at the factory.
However, it may be necessary to readjust the
in cident light module in some cases after trans­porting and setting up the stand. Therefore,
check the fi eld diaphragm centering.
The following procedure is provided for the inci­dent light-bright fi eld illumination.

• Select an objective with moderate magnifi ca­tion (10x–20x).

• Activate the incident light axis with the TL/IL
button (84.1).

• Press the IL-BF / Fluo button to activate the
bright fi eld 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).

Adjusting the fi eld diaphragm*

• Close the fi eld diaphragm with the FD button
(84.4) or manually until the edge of the dia­phragm (round or rectangular) appears in the
fi eld of view.

•

If the limits of the fi eld diaphragm are not in the
center of the fi eld of view, move the posi tion of the
fi eld 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
fi eld diaphragm to the point that they just dis-

appear from the fi eld of view.

• We recommend the use of a rectangular fi eld
diaphragm when using a digital camera. Match
the size of the diaphragm to the chip size of the
camera.

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. As a result of transport and setup of the
stand, however, in some cases centering maybe
be required again. Therefore check the center­ing.

Note:

Each objective has its own light ring assigned to
it in the condenser. The test must therefore be
performed for each objective.

Regular phase contrast with phase objectives

When choosing an objective suitable for phase
contrast, the appropriate light ring is selected
automatically when using a motorized con­denser. Otherwise, select the light ring manually.

7.8 Checking modulation contrast slit dia-

phragms

If your microscope is prepared for integrated
modulation contrast, its condenser will be
equipped with slit diaphragms suitable for the
objectives.
The slit diaphragms have been centered at the
factory.

Their proper location should be checked, how­ever.

• 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).

• Focus the ring structure (95a) by loosening
the clamping ring (93.2) somewhat and moving
the eyelens (93.1), or focus the Bertrand lens
(94.2).

• Retighten the clamping ring.

76

Note:

Each objective has its own slit diaphragm as­signed to it in the condenser disk. The test must
therefore be performed for each objective.

Open the cover at the top right side of the con­denser. The various
numbered openings for the inserts are now vis­ible. Ensure that all of the slit diaphragms are
fi rmly seated and that none of the retaining
screws are loose. If a part has loosened, please
see Chapter 6.5 Installation of Condensers.

For manual condensers, proceed as described
above for the DMI3000 B.

• Select the POL method (one of the variable
function buttons on the stand). If the analyzer
is present on the Fluo turret as an analyzer
block, it will move into position automatically. A
manual analyzer must be positioned by hand.

In the case of motorized condensers with mo-

torized polarizers, the polarizer will move into
position automatically.

• Insert the centering key in the opening provid­ed on the condenser (Fig. 96).

7.10 Adjusting the Light Sources

• The adjustment window shows the direct im­age of the arc and its mirror image. These are
generally not in alignment with one another.

In the lamp housing 106 z, the direct image of the
fi lament (in halogen lamps) or the arc (in gas dis­charge lamps) and its refl ection are focused sep­arately and adjusted in relation to one another.

An adjustment window (2.8, p. 21; 5b.3, S.25) 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 refl ector (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.
