3.10
3.10.1
3.10.2
Adjusting the Aperture Diaphragm
The setting of the aperture diaphragm affects
optical image resolution, contrast, depth of field,
and brightness. Turning the condenser aperture
diaphragm ring (or aperture diaphragm knob)
changes the size of the aperture diaphragm.
A small aperture diaphragm opening reduces
resolution and brightness but increases contrast
and depth of focus. A large aperture diaphragm
size increases resolution and brightness but
reduces contrast and depth of focus. These
characteristics involve inherent tradeoffs and
cannot be optimized independently. Generally,
aperture settings that are 70 to 80% of the
numerical aperture of the objective will provide
satisfactory images with suitable contrast.
Since an excessively small aperture diaphragm
opening will degrade image resolution, we do not
recommend setting the aperture diaphragm to less
than 60% of the objective's numerical aperture.
The numerical aperture is indicated on
the side of the objective.
Aperture diaphragm knob
Adjusting the aperture diaphragm opening using the condenser
scale
Since the condenser scale indicates the numerical aperture, adjust the aperture diaphragm ring
according to the scale.
(Normally, the index on the aperture diaphragm ring should align with a scale line that
corresponds to 70 to 80% of the numerical aperture of the objective.)
Adjusting the aperture diaphragm opening using the centering
telescope (optional)
Remove one eyepiece and attach the centering telescope in place using the optional adapter.
Turn the aperture diaphragm ring to stop down to the minimum aperture. While holding down
the flange of the centering telescope, turn the eyepiece of the centering telescope and focus on
the aperture diaphragm.
Turn the aperture diaphragm ring to adjust the aperture. (Normally, the aperture diaphragm
should be adjusted to around 70 to 80% of the size of the field of view.)
After the adjustment, remove the centering telescope and adapter and reattach the eyepiece.

Adjusting the Field Diaphragm
The field diaphragm controls the amount of
illumination falling on the area of the specimen
being viewed. Turning the field diaphragm knob
changes the size of the field diaphragm. For normal
observations, the size of the diaphragm should be
slightly wider than the boundary of the field of
view. Illuminating a broader area than necessary
will result in stray light entering the field of view,
generating flare and reducing image contrast.
Appropriate field diaphragm settings are
particularly important for photomicrography and
digital image capturing. In general, good results
will be obtained by stopping down the field
diaphragm to settings slightly wider than the area
to be reproduced within the photo frame or monitor
display.

3.13 Oil Immersion Operation
3.13
Oil Immersion Operation
Objectives marked “Oil” are oil-immersion
objectives. Objectives of this type are used with
immersion oil applied between the specimen and
the tip of the objective.
For maximum performance, oil-immersion
objectives with numerical apertures of 1.0 or higher
should be combined with oil-immersion
achromatic/aplanat condensers. Oil-immersion
condensers are used by applying oil between the
specimen and the condenser.
Any bubbles in the immersion oil will degrade image quality. Be careful to prevent bubbles from
forming. To check for air bubbles, fully open the field diaphragm and aperture diaphragm,
remove the eyepiece, and examine the exit pupil (bright round section) of the objective inside
the eyepiece tube. If it is difficult to ascertain the presence of bubbles, attach a centering
telescope (optional) with the adapter (optional), then look for air bubbles while turning the
eyepiece section of the centering telescope to adjust focus. If you detect bubbles, remove them
by one of the following methods:
• Turn the revolving nosepiece slightly to move the oil-immersed objective back and forth
once or twice. (In the case of the condenser, gently turn the condenser focus knob to
move the condenser up and down slightly.)
• Add more oil.
• Remove the oil and apply new oil.
Use as little oil as possible (just enough to fill the space between the tip of the objective and the
specimen, or between the tip of the condenser and the specimen). Too much oil will result in
excess oil flowing onto the stage and around the condenser.
Any oil remaining on the oil-immersion objective or adhering to the dry-type objective will
noticeably degrade image quality. After use, thoroughly wipe off all oil, and make sure that no oil
remains on the tips of other objectives. Additionally, carefully wipe off oil from the condenser.
Use petroleum benzine to wipe off immersion oil. For optimum results, we recommend following
up petroleum benzine with absolute alcohol (ethyl or methyl alcohol).
If petroleum benzine is unavailable, use methyl alcohol alone. When using just methyl alcohol,
note that surfaces will need to be wiped repeatedly to ensure complete removal of immersion oil.
Usually, three or four times should be sufficient to clean the lens.
CAUTION
When using petroleum benzine or absolute alcohol, always follow the
instructions provided by the manufacturer. These liquids are highly
flammable and must be kept away from flames and sparks.

Chapter 3 Individual Operations
3.14 Water Immersion
3.14
Water Immersion
Objectives marked “WI” or “W” are water-immersion objectives. These objectives are used with
immersion water (distilled water or physiological saline) applied between the specimen and the
tip of the objective. Microscopy procedures are the same as for oil-immersion objectives.
Since water evaporates readily, monitor the immersion water during observation. Avoid using
too much water, since excess water will flow onto the stage and around the condenser,
promoting corrosion.
After use, wipe off water from the tip of the objective and condenser, then follow up by wiping
with absolute alcohol.
If you observe water stains, apply a small amount of neutral detergent and wipe gently, then
follow up with absolute alcohol.

The field diaphragm is used to restrict the illumination to the area of the specimen being viewed.
Operating the field diaphragm lever changes the size of the field diaphragm. For normal
observations, stop down the diaphragm so that the aperture boundaries are just outside (or
inside) the field of view. Illuminating an area broader than necessary will result in stray light
entering the field of view, generating flare, reducing image contrast, and expanding the area of
the specimen subject to fading.

3.17 Selecting Fluorescent Filters
3.17
Selecting Fluorescent Filters
A filter cube is comprised of the following three
optical components: an excitation filter (EX filter),
a barrier filter (BA filter), and a dichroic mirror
(DM). Select a filter cube with the appropriate
combination of optical components for the
specimen characteristics, the fluorescent pigment,
and the purpose intended. Keep in mind the
following:
• Different combinations of excitation and barrier
filters may be selected for the same excitation
method.
• Other types of excitation filters, barrier filters,
and dichroic mirrors can be purchased
separately.
• Excitation filters are exposed to strong light
during operations and tend to age rapidly.
Replace the excitation filter at frequent
intervals.
CAUTION
When using the UV2A or UV2B, be sure to remove the spacer inside by
unscrewing the ring retaining the excitation filter. These filters cannot be used
until the spacer inside the ring has been removed.

3.17 Selecting Fluorescent Filters
3.17.1
Selecting excitation filters (EX filters)
Excitation filters allow selective transmission of
light (excitation light) in the waveband required for
fluorescent light emissions from the specimen,
blocking light of all other wavelengths. The range
of wavelengths allowed to pass through a filter is
referred to as bandwidth.
The range of the bandwidth of the excitation filter
determines the brightness of the fluorescent image,
the generation of self-fluorescence (fluorescence
resulting from substances other than fluorescent
pigments), and degree of fading. The broader the
bandwidth, the greater the amount of excitation
light irradiated onto the specimen, increasing
brightness. However, this also increases the
amount of self-fluorescence and causes faster color
fading. Narrow bandwidth reduces the amount of
excitation light striking the specimen and causes
the image to appear darker, but reduces
self-fluorescence and fading. For specimens with
pronounced self-fluorescence, use excitation filters
with a narrow bandwidth (note that this will make
the fluorescent image darker).

3.17.2
Selection of barrier filter (BA filter)
The barrier filter allows only fluorescent light emitted by the specimen to pass, blocking
excitation light. This allows viewing of a fluorescent image without excess illumination (dark
background).
There are two types of barrier filters: LP filters block all light below a certain wavelength but
pass all light of longer wavelengths. BP filters pass only light of a certain waveband, blocking all
other light. Use the filter type appropriate for your intended purpose.

3.17 Selecting Fluorescent Filters
LP filter (long-pass filter)
LP filters block all light below a certain wavelength
but pass all light of longer wavelengths. This border
wavelength is called a cut-on wavelength.
(1) For specimens dyed with a fluorescent
pigment in which the fluorescent waveband
and excitation waveband (light that the
specimen absorbs in order to emit fluorescent
light) are very close, select a barrier filter
with the shortest cut-on wavelength
permitted by performance requirements for
efficient fluorescent microscopy. If the cut-on
wavelength is long, excitation light and
fluorescent light will be entirely distinct,
tending to darken the background of
fluorescent images. However, recent
advances in filter performance have resulted
in increased use of filters of short cut-on
wavelengths.
(2) For multiple-dye specimens, use an LP filter
for microscopy of fluorescent images of all
dyes. Note that a combination involving an
ordinary dichroic mirror, an excitation filter,
and an LP-filter-type barrier filter will be
incapable of exciting dyes that emit
long-wavelength fluorescent light – for
example, TRITC in the case of FITC and
TRITC. This will result in very dark TRITC
fluorescent images. For such cases, we
recommend using multiband filters.
BP filter (bandpass filter)
The bandpass filter passes only light of a certain
wavelength, blocking all other wavelengths.
BP filters are used for microscopy of fluorescent
images involving a specific dye in multiple-dye
specimens. (For example, in a double-dye
specimen of FITC and TRITC, the BA520-560 filter
enables microscopy of just the FITC fluorescent
image.)
However, BP filters will not indicate
self-fluorescence, if any (because the fluorescent
image in the above combination is green only). LP
filters are better suited for making fine distinctions
in self-fluorescence based on slight color
differences.

Replacing excitation and barrier filters
Excitation and barrier filters can be removed from
the filter cube and replaced. (Dichroic mirrors
cannot be dismounted from the filter cube.)
Excitation filters are screw-in filters.
Barrier filters are slide-in filters. Align the
projection on the barrier filter with the groove on
the filter cube and turn clockwise approximately 30
degrees to secure in place.
Filter cube internal spacers
The filter cubes listed below cannot be inserted
directly into the Epi-fl attachment. Instead, as
described below, an internal spacer must first be

3.18 Image Capture
3.18
3.18.1
3.18.2
Image Capture
Images can be captured by attaching a camera head to the ergonomic binocular tube or
trinocular eyepiece tube.
For more detailed discussion of this topic, refer to the operating manual provided with the
camera head or camera control software.
Proper adjustment of light intensity and focus on the microscope side are important for obtaining
clear images. Listed below are key considerations in capturing clear images.
Adjusting light intensity
Lamp voltage: When the 50i is used in applications for which accurate color reproduction is
critical, set the brightness control knob at a midpoint and use ND filters to make
brightness adjustments.
Filter: Place a commercially available color compensation filter on the filter holder at the
microscope base, as necessary.
Adjusting the condenser
• Always focus and center the condenser.
3.18.3
3.18.4
• Center the annular diaphragm for phase contrast microscopy.
• For normal operations, set the diaphragm aperture to 70 to 80% of the N.A. of the
objective.
Confirming the photomicrographic range
The image on the monitor represents the photomicrographic range.
Confirming focus
Check focus by viewing through the eyepiece and viewing the monitor. If the focal positions for
the two images differ, adjust the focal position adjustment screw at the camera port.
58
Chapter 3 Individual Operations
3.18 Image Capture
3.18.5
3.18.6
3.18.7
Making adjustments to keep out extraneous light
Field diaphragm: Stop down the diaphragm to a setting just slightly wider than the area shown
on the monitor.
Eyepiece: Cover the eyepiece with a cloth.
3
Anti-vibration measures
If the exposure is less than 1/8 of a second, reduce light intensity with ND filters to make
exposures longer than 1/8 of a second. (If accurate color reproduction is not important, you can
use the brightness control knob to reduce light intensity.)
Fluorescence photomicrography
The fluorescence of fluorescent specimens may fade during exposure. To prevent this, do the
following:
(1) Select a brighter optical combination.
Even if the overall magnification is the same on the monitor, the combination of
objective and camera zoom can result in significant variations in exposure time. We
recommend increasing the magnification with the objective rather than the zoom.
(Generally, the aperture of the objective increases with magnification. The larger the
numerical aperture, the brighter the resulting image.)
(2) Adjusting the excitation light
Excessively bright excitation light will accelerate specimen fading while making it more
difficult to acquire suitable fluorescent images. Use ND filters to adjust brightness.
(3) Specimen
Photomicrography of faded specimen sections requires prolonged exposure times and
results in poor color reproduction and low-quality images. Move the specimen to obtain
images from a fresh section of the specimen previously unexposed to excitation light.
For best results, use the differential interference contrast or phase contrast methods to
select a specimen section for photomicrography, and then switch to the fluorescent
method to capture images.
(4) Supersensitive TV camera (other than DS-5M)
Under certain conditions, it may help to place an IR (infrared ray) blocking filter in
front of the supersensitive TV camera sensor. Experiment with the IR blocking filter to
determine its characteristics.

• Use only the battery charger specified for use with the EN-EL1.
• Before storing the battery for extended periods, fully recharge, then fully
discharge the battery. (This should be done at least once a year.)
• Remove the battery from the microscope or battery charger when not in use.
If the battery remains attached, it may overdischarge and become unusable,
since a trace current flows even when power is turned off.
• Store the battery in a cool place when not in use.
・ Ideally, store in locations with ambient temperatures around 15°C to 25°C
and low humidity.
・ Avoid unusually cold or hot locations.
• Recharge the battery at room temperature (5°C to 35°C).
• To avoid degrading battery performance, do not recharge the battery until it
has been in use for some time and is at least partially discharged.
• Battery temperature may increase somewhat immediately after recharging.
This does not indicate a problem, and battery performance will not be
affected.
• If battery life declines significantly, even after a full recharge, the battery

Care and Maintenance
7.1
Lens Cleaning
Keep the lens free of dust, fingerprints, etc. Dirt on the lenses or filters will affect image quality.
If any of the lenses become dirty, clean them by the procedure given below.
• Brush away dust with a soft brush or wipe away gently with gauze.
• If fingerprints or grease gets on a lens, moisten a piece of soft, clean cotton cloth, lens
tissue, or gauze with absolute alcohol (ethyl or methyl alcohol) and wipe.
• Use petroleum benzine only to remove immersion oil from the objective. For optimum
results, we recommend following up petroleum benzine with absolute alcohol (ethyl or
methyl alcohol). If petroleum benzine is unavailable, use methyl alcohol alone. When
using just methyl alcohol, note that surfaces will need to be wiped repeatedly to ensure
complete removal of immersion oil. Usually, three or four times should be sufficient to
clean the lens.
• Never use petroleum benzine to clean the entrance lens at the bottom of the eyepiece
tube or prism surface of the eyepiece tube.
• Absolute alcohol and petroleum benzine are highly flammable. Be careful when handling
these materials, particularly around open flames or when turning the power switch on or
off.
• Follow the instructions provided by the manufacturer when using absolute alcohol.
