CAUTION
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.
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 "Cleaning Filters and Lenses" of "VII.
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.
