6. When viewing in the near-infrared range, use the cut-off
filter (4) with transmission from 700 nm and further. When
viewing the reflected radiation, use a metallic surface as a
reflector. Any paper surface absorbs the radiation greatly.
7. For "goggle" operation, place the IR viewer onto "dove tail"
of face mask and сlamp it with screw. Adjust the position
with fixing screws for the most convenient operation
The Maintenance instruction
1. During the IR viewer operation there is no danger of
electric shock.
2. When brought into a warm room from the cold outside the
optical elements may become wet.
3. Prevent the viewer from mechanical damage and
moisture.
4. Protect the lenses from dirt. If necessary, clean them with
clean soft cloth; remove oiled spots or deposit with cotton
wool slightly wetted in rectified alcohol or with alcohol-
ether mixture.
5. If necessary, unscrew the lens and clean the
photocathode, because the dust can be viewed through
hole of cover of the lens.
