Physically, the night-vision goggles are made in the form of two
identical electro-optical channels – monocular (3) and monocular (4) –
which are mechanically linked with each other with the aid of guide (1)
and guide (2). Each of the monocular pair incorporates lens (5), eyepiece
(6), image-intensifier tube (7) and barrel (8).
RH side monocular (3) that allows the pilot to carry out observation
with the right eye is rigidly fastened to guide (2), while LH side monocular (4)
that permits observation with the left eye is of a movable design and may
be displaced to adjust the eyepieces of the night-vision goggles to suit the
pilot’s eyes.
To adjust the night-vision goggles interpupilary distance, depress
button (10) and displace monocular (4) along guide (2) to set it to the
desired position. These done, release the button to fix monocular (4) in
the selected position.
Batteries (11) are installed inside guide (2) and closed with cap-
switch (12).
The night-vision goggles are attached to the helmet with the aid of
the guides of fixing assembly (13) and those of the helmet mount. The
fixing assembly is retained in the fixed position in the helmet mount by
means of retainer (14).
The transfer of the night-vision goggles from the stowed position to
the operating one, in which they are fitted on the helmet, is accomplished
by depressing button (15) with the left hand and lowering the goggles until
they are retained in the locked position. The fixing assembly is provided
with a connector, for connecting the mating connector plug of cable (16),
intended to feed power to the night-vision goggles via the voltage
converter.
Upon termination of use, the night-vision goggles are easily
removed complete with cable (16) from the mount of the helmet by
pressing down lever (17).
