When you use the external light source using a mercury lamp or so on, handle the lamp with
extreme caution. Read the manual for the light source carefully and observe handling
precautions.
4. Ratings of power supply
The power circuit in this instrument is rated for AC power supplies of 100 to 240 V, 50/60
Hz. When connecting the instrument to a power line, check that the line conforms to the
voltage and frequency ratings mentioned above.
Use of a power line that does not satisfy the ratings may lead to equipment malfunction or
damage or a fire.
5. Power cord
Use only the supplied power cord. Using the wrong power cord could result in damage or a
fire. Also, connect the microscope to a PE (protective earth) terminal, since the microscope
complies with the electric shock protection class I.
And besides, to prevent electrical shock, always turn off the power switch (flip it to “ ”
side) before connecting or disconnecting the power cord.
For details about the specified power cord, see “VII. Specifications.”
6. Specified light source

WARNING
7. Light source other than the specified ones
To perform the epi-fl microscopy with the LV-UEPI2 illuminator, the specified light source
brightness may be less than the desired brightness. In this case, a light source other than the
specified ones, an external light source, can be used for the LV-UEPI2.
Use the X-Cite 120 (manual type) or X-Cite 120PC (motorized type) manufactured by
EXFO Electro-Optic Engineering Inc. for the external light source.
Note that if a light source other than the specified ones are attached to this microscope, this
microscope system will not be treated as a UL-Listed product.
8. Heat from the light source
The lamp and the lamphouse become extremely hot. To avoid burns, do not touch the
lamphouse while the lamp is lit or for thirty minutes after it is turned off.
Furthermore, to avoid the risk of fire, do not place fabric, paper, or highly flammable
volatile materials (such as gasoline, petroleum benzine, paint thinner, or alcohol) near the
lamphouse while the lamp is lit or for about thirty minutes after it is turned off.
9. Air vents
Do not block the air vents on the microscope and lamphouse.
If the air vents are blocked, the temperature of the microscope will raise. And it results in
damage or fire.
10. Ultraviolet light from a light source other than the specified ones
If you use a light source other than the specified ones and that has a mercury lamp or so on,
the light source radiates ultraviolet light that is harmful to the eyes and skin from the
emission port. Direct viewing of light from these lamps may result in snow blindness at a
light case or blindness at worst. To prevent injury, follow the guidelines below.
1) Insert the UV collector lens into the optical path of the microscope unless the
UV excitation light is necessary.
On the illuminator LV-UEPI2, the UV filter automatically enters the optical path when
turning the microscopy selection knob to BF (bright-field) or DF (dark-field). The UV
filter is removed from the optical path when turning the knob to FL1 (epi-fl 1) or FL2
(epi-fl 2).
2) When performing the epi-fl microscopy by using the UV excitation light, attach
the filter cube dedicated to the UV excitation light. And then, if you must see
the objective or its surroundings, be sure to see through the ultraviolet light
shield.
3) Attach the light source to the microscope during use.
Always attach the light source to the microscope when the light source is ready to turn
on. Do not turn on the light source unattached to the microscope, or remove the light
source from the microscope while the light source is lit. When removing the light source
from the microscope, turn off the power to the light source, and then unplug the power
code from the wall outlet.
11. Reflection
Lustrous samples reflect the illumination. Do not observe the illuminated surface of a
sample for a long time because the strong reflection may hurt your eyes. When you use the
illuminator LV-UEPI2, be sure to view it through the ultraviolet light shield.
3
CAUTION
1. Handle the system gently.
Components of this system are precision optical instruments. Handle them carefully, and do
not subject them to any shocks.
The precision of the objectives in particular can be adversely affected even by weak shocks.
2. Do not wet the microscope
If the microscope gets wet, a short circuit may cause malfunction or abnormal heating of the
microscope. If you accidentally spill water on the microscope, immediately turn off the
power switch (flip it to the “ ” side) and unplug the power cord from the wall outlet. Then,
wipe away the moisture using a dry cloth or the like. If water gets inside the microscope, do
not use it; instead, notify your nearest Nikon representative.
3. Weak electromagnetic waves
This microscope emits weak electromagnetic waves. The accuracy of any precision
electronic equipment may be adversely affected if positioned too close. If the microscope
affects TV or radio reception, move the radio or TV farther away from the microscope.
4. Installation location
Being a precision optical instrument, the microscope may get damaged or loose accuracy if
it is used or stored under unsuitable conditions. When selecting the installation location,
note the following:
• Avoid a brightly lit location, such as exposed to direct sunlight or directly under a room
light. The image quality deteriorates if there is excessive ambient light.
• Always install the microscope with a surrounding clear area of 10 cm or more.
• Choose a location that is free from considerable dust or dirt.
• Choose a flat surface with little vibration.
• Choose a sturdy desk or table that is able to bear the weight of the instrument.
• Do not install the microscope in a hot and humid location.
• Select a layout that allows easy removal of the power cord from the microscope’s AC inlet
in the event of an emergency.
• For details about the operating environment and storage environment, see “VII.
Specifications.”
5. Cautions on moving the microscope
• The microscope is a precision optical instrument. Handle it carefully and do not subject it
to a strong physical shock. (In particular, objectives may loose accuracy when exposed to
even a weak physical shock.)
• When moving the microscope, first remove the stage and the lamphouse. Then, securely
hold the microscope by the root of the arm from the back.
(Information) The microscope with the stage, eyepiece tube, lamphouse, and other parts
attached, weighs approx. 20 kg.
• Do not hold the focusing knobs, eyepiece tube, lamphouse, sub-stage, etc., when carrying
the microscope. They may come off and may cause serious injury or malfunction.
• Before carrying the stage, attach the fixing metals to hold the movement of the stage plate.
• Be careful not to pinch your fingers or hands during transportation.
6. Cautions on assembling the microscope
• Be careful not to pinch your fingers or hands during assembly.
• Scratches or fingerprints on the lens surface will adversely affect the microscope image.
Be careful not to scratch or touch the lens surfaces.
4
CAUTION
7. Cautions on lamp replacement
• To prevent burn injury, allow the lamp to cool down sufficiently (for at least 30 minutes
after it is turned off) before replacing the lamp.
• To prevent electrical shock and damage to the microscope, always turn off the power
switch (flip it to the “ ” side) and unplug the power cord from the wall outlet before
connecting or disconnecting the lamphouse.
• Do not touch the glass surface of the lamp with bare hands. Fingerprints or grease on the
bulb surface will reduce the illumination intensity of the lamp. Wipe out any fingerprints
or grease attached to the surface.
• Securely attach the lamphouse cover to the lamphouse after replacing the lamp. Never
light the lamp while the lamphouse cover is open.
• When you dispose of the replaced lamp, do not break it up. Instead, dispose of the used
lamp as special industrial waste or dispose of it according to the local regulations and
rules.
8. Handing of filter cubes
When using the microscope configured with the illuminator LV-UEPI2, a filter cube can be
attached to enable epi-fl microscopy. Note the following precautions for handling a filter
cube.
• Interference filters (in particular, excitation filters exposed to intense light) are subject to
aging. Replace them depending on their total operating hours.
• Filters can change in characteristics under high humidity. To avoid changes in
characteristics and quality, do not use or store filters at high temperatures or high
humidity, or expose them to rapid temperature changes. When not using filters, they
should be stored with a drying agent in desiccators or sealed containers.
• The filters fitted in the nine types of filter cubes listed below have sharper wavelength
characteristics than ordinary filters. However, these filters should be handled with care as
they are applied with complicate coating. In particular, be cautious against wear during
cleaning. (Observe the procedures described in “1. Cleaning Lenses and Filters” of “VI.
Care and Maintenance.”)
Single-band filter cubes: DAPI, FITC, TxRed, and GFP
Multi-band filter cubes: F-R, F-T, D-F, D-F-R, and D-F-T.

Coarse focus stopper
The coarse focus stopper restricts the movement of the coarse focus knob so that the stage cannot
be raised higher than the position the operator specifies.
When the coarse focus stopper ring is rotated in the direction of the arrow (labeled “CLAMP→”)
on the microscope base, the coarse focus knob cannot be used to move the stage any higher.
(Movement of the stage by the fine focus knob is not restricted.)
For example, once the coarse focus knob is clamped in place at the focus position, a rough focus
can be attained the next time simply by raising the stage until the coarse focus knob cannot be
turned any further.
If the coarse focus stopper is not being used, be sure to turn the ring in the direction opposite to the
arrow on the microscope base as far as it goes.

When changing the sample, lower the stage by
turning only the coarse focus knob.
After changing the sample, gently raise the stage
by turning only the coarse focus knob as far as it
goes. The sample should be roughly in focus when

Diopter Adjustment
Diopter adjustment compensates for differences in eyesight between your left and right eyes. After
the correct adjustment, you will find the observation with both eyes easier and the focus shift is
reduced when switched to different objectives. Be sure to adjust the diopter adjustment rings on
both eyepieces.
1 Turn the diopter adjustment rings on both eyepieces to align their engraved lines with the
edge of the outer tube of the eyepiece. (This is the standard position for diopter adjustment.)
2 Focus on the sample with the 10x objective following the steps of bright-field microscopy
under the epi-illumination (p.14, 15) or under the dia-illumination (p.24, 25).
3 Bring the 50x objective into the optical path and focus on the sample by turning the coarse/
fine focus knobs.
4 Bring the 5x or 10x objective into the optical path.
5 Focus on the sample by turning the diopter adjustment ring on the right eyepiece (not the
coarse/fine focus knobs).
Look through the left eyepiece with your left eye, and the right eyepiece with your right eye,
to focus on the sample with the diopter adjustment rings.
6 Repeat steps 3 to 5 with the 50x and 5x (or 10x) objectives until the image stays in focus
even though the objective magnification is changed.

Adjusting the Epi-illumination
(Field Diaphragm and Aperture Diaphragm)
Field diaphragm
The field diaphragm restricts illumination on the sample to the area
being observed.
The field diaphragm open/close lever changes the size of the field
diaphragm. Adjust the size of the diaphragm until it circumscribes or
inscribes the viewfield.
Illuminating an area larger than necessary can let in stray light,
creating flaring and reducing the contrast of the optical image.
Proper operation of the field diaphragm is important for the
photomicrography. Generally, the field diaphragm should be set to an
area slightly larger than the area to be exposed on film, that is, the
photographed area.
Be sure to adjust the field diaphragm after centering it.

Aperture diaphragm
Since the aperture diaphragm is for adjusting the numerical
aperture of the illumination system, this diaphragm is related to
the resolution, contrast, and depth of focus of the optical image.
The aperture diaphragm open/close lever will change the opening
of the aperture diaphragm. Remove one of the eyepieces, and then
adjust the aperture diaphragm opening while observing the
objective’s exit pupil in the eyepiece tube.Generally, the aperture
diaphragm should be adjusted to about 70 to 80% of the
numerical aperture of the objective.
The diaphragm image may not appear in the case of samples with
low reflectivity. In this case, change to a sample with a nearpolished surface.
For the illuminator LV-UEPI, the aperture diaphragm centering
has been adjusted at the factory and dose not need to be adjusted.

Polarizer
Placing the polarizer in the optical path
• For the LV-UEPI:
Remove the dummy slider at the right side of the illuminator, and in its place, insert the polarizer
slider with its orientation indication facing toward the eyepieces. (p.55)
• For the LV-UEPI2:
Remove the vertically oriented cover at the right side of the illuminator. Insert the polarizer slider
into the rear slot with its orientation indication facing toward the eyepieces. In the front slot, insert a
dummy slider or lambda plate slider. (p.55)
• Insertion to the optical path:
Pushing the polarizer slider in to the first clickstop position inserts the empty hole into the optical
path. Pushing it further in to the second clickstop position inserts the polarizer into the optical path.
Set the orientation of the polarizer by turning the polarizer rotating dial.
Removing the polarizer out of the optical path
With the polarizer placed in the optical path, pull it out in the right direction to the first clickstop
position. The polarizer has been removed out of the optical path (instead, the empty hole is now in
the optical path).

Place the polarizer and the analyzer in the optical
path. Place a sample with a flat and plain surface on
the stage and set the microscope for simplified
polarization microscopy under the epi-illumination.
Remove one eyepiece from the microscope and look

III. Operation of Each Part
Filter Cubes for Fluorescence Observation (for the LV-UEPI2 only)
The illuminator LV-UEPI2 accommodates two filter cubes for
Barrier filter
epi-fluorescence observation.
The filter cube consists of an excitation (EX) filter, barrier (BA)
UV-2A
filter, and dichroic mirror (DM). Note the following
considerations as a guideline and choose the right combination of
filters that are most suitable for the characteristics of the sample
and fluorescent stain.
• Different combinations of excitation filter and barrier filter are
available for the same excitation method.
Excitation filter
Dichroic mirror
(housed inside)
• Excitation filters, barrier filters, and dichroic mirrors can be
purchased separately.
• Excitation filters will deteriorate over time since they are exposed to intense light. Replace them
as necessary.
• For the procedures to attach filter cubes, see page 56 of “IV. Assembly.”

Light source for the epi-fl microscopy
To perform the epi-fl microscopy with the LV-UEPI2 illuminator, the specified light source
brightness may be less than the desired brightness. An external light source suitable for the
excitation method can be installed into the LV-UEPI2 for this purpose.
* Please take note that if a light source other than the specified ones are installed onto this
microscope, this microscope system will not be treated as a UL-listed product. Nikon
recommends that the light source to be installed onto this microscope should have been
tested by a safety certification organization.
Selecting an excitation (EX) filter
The excitation filter selectively transmits only the light of the
EX filer
wavelength range required for the sample to fluoresce, while
Bandwidth
blocking the other light. The wavelength range of light that
can pass through the filter is called the bandwidth. The
bandwidth of an excitation filter determines the brightness of
fluorescence image, the occurrence of self-fluorescence
(fluorescence generated by materials other than the fluorescent
0
Wavelength
stain), and the degree of fading. A wider bandwidth delivers
more excitation light to the sample and makes the image brighter, but it induces more selffluorescence and therefore more fading A narrower bandwidth delivers less excitation light to the
sample and makes the image darker, but it induces less self-fluorescence and therefore less fading.
If self-fluorescence is too intense, use an excitation filter of narrower bandwidth. (The fluorescence
image becomes darker, however.)
Excitation filters will deteriorate over time since they are subject to intense light. Replace them as
necessary depending on their total operating hours.

Selecting a barrier (BA) filter
The barrier filter transmits only the fluorescence emitted by the sample, blocking the excitation
light. This enables observation of fluorescence images having less unnecessary light (darker
background).
BA filters are available in two types: long-pass (LP) and band-pass (BP). The LP filter blocks all
the light of shorter wavelength than a given value. The BP filter transmits light in a given
wavelength range. Use the suitable types in accordance with your purposes.

advancement in filter performance, however, shorter cut-on wavelengths are used more often
than before.
2) LP filters are used for samples stained in multiple colors where fluorescence images for all the
colors are desired.
However, the usual combination of a dichroic mirror, an excitation mirror, and a barrier filter of
LP filter type, may not be sufficient to excite a stain that emits fluorescence of longer
wavelength (for example, TRIC when the sample is stained with FITC and TRITC), making the
fluorescence image for TRITC very dark. In a case like this, a multi-band filter is recommended.

say FITC and TRITC, and fluorescence images due only to
FITC are desired, then BA520-560 should be selected.)
If a BP filter is used, however, any self-fluorescence cannot
be discriminate (because the fluorescence image will be green
all over for the above combination).
The LP filter is more useful when you wish to discriminate
self-fluorescence by a subtle difference of hue.

2. Sliders (dummy sliders, polarizer slider, lambda plate slider, and analyzer slider)
• For the LV-UEPI:
The sliders are to be inserted into the slots on the front and the right side of the illuminator. In case
of dummy sliders, slide them in till the limit (so that the empty hole will be set in the optical path).
• For the LV-UEPI2:
The LV-UEPI2 has covers over the slider slots. Remove the covers before inserting sliders.
For sliders that are not in use, the covers can be set in place, eliminating the need of inserting
dummy sliders.
Note that the slots for polarizer slider and lambda plate slider share a single cover. When using only
a polarizer, therefore, insert a dummy slider in front of the polarizer slider.
3. Filter sliders and filters
1 Remove each filter slider from the illuminator.
(There are two sliders.)
2 Pull out the locking plate from the filter slider.
3 Insert the desired filter. (Two filters can be set on the
filter sliders.)
4 Reinstall the locking plate.
5 Affix the label to the appropriate lug of the filter
slider.

VI. Care and Maintenance
1
Cleaning Lenses and Filters
Do not let dust, fingerprints, etc., get on lenses and filers. Dirt on lenses, filters, etc., will adversely
affect the view of the image. If any lens gets dirty, clean it as described below.
• Either brush away dust with a soft brush, or wipe it away gently with gauze.
• Only in cases of fingerprints or grease, dampen a piece of soft, clean cotton cloth, lens tissue, or
gauze with absolute alcohol (ethyl or methyl alcohol) and wipe.
• Absolute alcohol requires care in handling as it is highly flammable. Be careful when using fire
or turning on/off the power switch nearby.
• Follow the instructions provided by the manufacturer when using absolute alcohol.
2
Cleaning the Painted, Plastic, and Printed Parts
Do not use organic solvents (alcohol, ether, and paint thinner, etc.) on painted, plastic, or printed
parts. Doing so could result in discoloration or in the peeling of printed characters. If the dirt is hard
to remove, wipe it gently using a piece of gauze dampened with a neutral detergent solvent.
3
Storage
Store the microscope in a dry place where mold is not likely to form.
Store the objectives and eyepieces with a drying agent in a desiccator or similar container.
