WARNING
7. To use an external light source
To perform an epi-fl microscopy with the LV-UEPI2A epi illuminator, the brightness of the
specified light source may be less than the desired brightness. In this case, the light source
described below can be used for the LV-UEPI2A epi illuminator.
• Light source
Nikon Inensilight C-HGFIE HG Precentered Illuminator (model name: C-HGFIE, electric operation
type) or X-Cite 120 PC (electric operation type) made by EXFO Electro Optical Engineering Inc.
If a manual operation type light source is attached, you cannot control the shutter and the
brightness on the microscope. Make sure to use the light source specified above.
Note that if the light source described above is used with the product, the product is not
approved as a UL listed product.
8. Heat from the light source
The lamp and the lamp house become extremely hot. To avoid burns, do not touch the lamp
house 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 lamp house 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 the lamp house. If the air vents are
blocked, the temperature of the microscope will rise. And it results in damage or fire.
10. Ultraviolet light from an external light source
If you use an external light source other than the specified ones and that has a mercury lamp, a
xenon lamp, or so on, the light source radiates ultraviolet light, which 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 the worst case. To prevent injury, follow the guidelines below:
1) Place a UVC collector lens into the optical path of the microscope unless the
UV excitation light is necessary.
On the LV-UEPI2A epi illuminator, an UV filter automatically enters the optical path when
the microscopy method is turned to the bright-field microscopy or the dark-field
microscopy. The UV filter is removed from the optical path when the microscopy method
is turned to the epi-fl microscopy 1 method (FL1) or the epi-fl microscopy 2 method (FL2).
2) When performing the epi-fl microscopy by using the UV excitation light, attach
the filter cube dedicated to the UV excitation light. If you must see the objective
or its surroundings, be sure to see through the ultraviolet light shield.
3) Use the light source with the microscope.
The light source device is required to be connected to the microscope whenever the light source
device is energized. Do not turn on the light source if it is not connected to the microscope, and
do not disconnect the light source from the microscope while the light source is lit.
When disconnecting the light source from the microscope, turn off the power to the light
source, and then unplug the power cord from the wall outlet.
11. Reflection
Lustrous specimens reflect the illumination. Do not observe the illuminated surface of a
specimen for a long time because the strong reflection may hurt your eyes. Make sure to see
the specimen through the ultraviolet light shield.
12. Cautions on operating the motorized units
The product can be controlled on a PC with “NIS-Elements,” the software for digital
cameras, when a digital camera is used with the product. To avoid unexpected injuries, note
the following when operating this product with a PC.
Before operating the product, check all moving parts for your safety.
• If you touch the nosepiece, objectives, or parts on the stage during operation, it may cause
injury to hands or fingers. Do not touch these devices or parts when operating.

CAUTION
7. Cable routing
8. Cautions when replacing lamps
9. Notes on handling a filter cube
Make sure the cables are routed properly. Do not bring the cables into contact with the lamp
house for the diascopic illumination. If a cable comes into contact with the lamp house, the
cable sheath may melt and it results in an electrical shock or fire.
• To prevent burn injuries, wait at least 30 minutes after the lamp is turned off to give it
sufficient time to cool down when replacing lamps.
• 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 outlet before attaching
or detaching the lamp house.
• Never touch the glass surface of the lamp with bare hands. Doing so will cause
fingerprints, grease, etc. to burn onto the lamp surface, reducing the illumination. If you
do get any fingerprints or dirt on the lamp, wipe them clean.
• Make sure the lamp house cover is securely fitted to the lamp house after replacing lamps.
Never turn on the lamp with the lamp house cover removed.
• 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.
When using the product configured with the illuminator LV-UEPI2A, a filter cube can be
attached to enable epi-fl microscopy. Note the following precautions for handling a filter
cube.
• Interference filters (especially excitation light filters, which are exposed to strong light)
deteriorate over time. Replace them depending on their total operating hours.
• Filter characteristics may alter if the filter is exposed to high humidity. To prevent
changes or degradation of filter characteristics, avoid using or storing the filters under
conditions of high humidity or high temperature and avoid subjecting the filters to rapid
temperature changes. When a filter is not in use, store it in a desiccator or hermetically
sealed container with a drying agent.
• The filters attached in the nine types of filter cubes listed below have sharper wavelength
characteristics than standard filters. However, due to their sophisticated coatings, they
must be handled with special care. In particular, take care to avoid abrasion from cleaning.
Observe the procedures described in “1. Cleaning Lenses and Filters” of “VI. Care and
Maintenance.”
Single band filter cubes: DAPI, FITC, TxRed, GFP
Multi band filter cubes: F-R, F-T, D-F, D-F-R, D-F-T
10. Software setup works after assembly

Microscopy Method
CAUTION
This chapter explains the procedure of each microscopy.
• See “IV. Assembly,” when the microscope has not been assembled yet.
• For detailed information about operations of parts of the microscope, refer to “III. Operation of
Each Part.”
Before performing microscopy
• Before using the microscope, please set up the LV100DA-U using “LVSetup” on a
PC contained in “LV Series Support Tools.”
• In this chapter, the microscopy is described with the interlock control of LVSetup
set to the Default mode. When the interlock control mode is set to the Optional
mode, the microscope may behave differently from the ways that are described in
this chapter.
• The interlock control of each electrically-driven device can be enabled using
LVSetup. When this function is enabled, the corresponding electrical devices are set
to the predetermined conditions in accordance with the microscopy method or
objective. If the interlock control is disabled, please be sure to operate each device
manually.
• For operations of LVSetup, see “LV Series Setup Tools Software Manual.”
• Motorized units can be controlled on a PC with “NIS-Elements,” the software for
digital cameras, when a digital camera is used with the product. For details, see the
instruction manual for the “NIS-Elements.”

Helpful tips
It may be difficult to focus on a specimen with small contrast, such on a polished surface. In a
case like this, reduce the opening of the field diaphragm so that its image can be seen in the
viewfield, and try to focus on the frame of the diaphragm image. When the frame is in focus, the
specimen is in focus just as well.

Differential Interference Contrast Microscopy under the Epi Illumination (Prism Slide Method)
5
Methods of the differential interference contrast (DIC) microscopy vary among the nosepiece
configuration. For motorized universal quintuple nosepieces, the LV-NU5A and the LV-NU5AC,
the prism slide method is used for the DIC microscopy under the epi illumination.
Attach the accessories required for the prism slide method of the DIC microscopy
1
under the episcopic illumination.
The accessories required for the prism slide method of the DIC microscopy under the episcopic
illumination are as follows:
• Motorized universal quintuple nosepiece (LV-NU5A or LV-NU5AC) (See Page 79.)
• LU objective (See Page 93.)
• Polarizer slider (for the episcopic illumination) (See Page 83.)
• Analyzer slider (See Page 83.)
• Lambda plate slider (for the sensitive color microscopy) (See Page 81.)
• DIC slider (L-DIC/L-DIHC, attached to the DIN slot of the nosepiece) (See Page 83.)
* Set up the microscope according to the "LVSetup" and set information of objectives correctly.
Focus on the specimen with the bright-field microscopy under the episcopic
2
illumination.
(See Pages 15 and 16.)
Set the microscope for the DIC microscopy under the episcopic illumination.

1 Push in the analyzer slider to place the analyzer
into the optical path. (See Page 60.)
2 Push in the polarizer slider to place the polarizer
into the optical path, and set the crossed Nicols
position by aligning the index. (See Page 57.)

indicated on the objective.
1 Place the NCB filter into the optical path.
(See Page 44.)
2 Push in the lambda plate slider to place the lambda
plate into the optical path. (See Page 62.)
This microscopy method makes the background
color of the field of view a sensitive color and
enables the microscopy with a high color contrast.
If the refraction index or the thickness of the
specimen changes, interference color corresponding
to the amount of change is seen.
Return to the bright-field microscopy under the
