.4. The main components of the article are the sighting device 3 (Figure A.2),
the illuminator 2, the handle for fastening the illuminator on the sighting
device for carrying the sighting device, the tripod 5 on which angle measuring
device 4 with the sighting device are fastened.
.4.2 The operation principle of the sighting device is based on the electro-
optical intensification of the image brightness of the objects (targets) at night
to such degree which is sufficient for eye observation.
.4.3 The sighting device operation at night is provided by the IIT A2 (Figure A.) of
heightened sensibility with micro channel intensification and automatic adjustment
of the screen brightness. The image of objects with little brightness is projected to
the photocathode of the IIT A2 by the objective , the IIT is located in the focal plane
of the objective .
The object image with intensified brightness on the screen of the IIT A2 is
transferred to the plane of the reticle 3 by the erector 2 and is viewed together
with the reticle 3 through the ocular 4.
.4.4 The figure A.6 shows the field of view of the sighting device (each
angle dimension between the lines presents one-thousandths part of the real
distance).
.4.5 When the switch SA (Figure A.) is switched on, 2.0 – 3.6 V voltage is
given to the IIT from the power supply G and G2.
.5. The sighting device3 (Figure A.2) consists of the following parts:
– the objective (Figure A.3) which is intended for projecting image of the
observed aim of little brightness to the photocathode of the IIT A2 (Figure A.);
– the ocular 8 (Figure A.3) which is intended for observation of the object.
.5.2 The sighting device has the following controls:
– the handle 2 which is intended for switching on the sighting device and
for switching on the reticle illumination;
– the diopter ocular setting ring 5 which allows to adjust the ocular according
to the diopters of the observer;
– the handwheel 2 which is intended for obtaining sharp image of the
observed object at the corresponding distance and for the compensation of
defocusing when the temperature changes from +50 to –50 °C.
.5.3 The tripod 5 (Figure A.2) is intended for fixing the sighting device 3 with
the angle measuring device 4 on the ground while working with the sighting
device in lying or sitting position.
Adjusting of the tripod height is carried out with the help of the telescopic
supports (Figure A.4), whose position is fixed with the help of the nuts 2.
The strap 3 is intended for tightening of the legs 4 during transportation.
When stored and transported in the case, the tripod is put into the soft cover 7
(Figure A.9).
0
.5.4 The angle measuring device 4 (Figure A.2) is intended for the
following:
– setting of the sighting device 3 on the tripod and its horizontal and vertical
aiming at the object of observation;
– orientation of the sighting device with the help of the aiming circle
corresponding to the direction of the magnetic meridian (North-South);
– measuring of the horizontal, vertical and direction angles.
.5.5 The angle measuring device has the following parts and controls:
– the handwheel 8 (Figure A.4) for the sighting device aiming in the horizontal
plane. The value of the horizontal angles is read on the scale 7 while observing
through the lens 5;
– the handwheel 3 for the sighting device aiming in the vertical plane. The
value of the vertical angles is read on the scale through the lens 2.
The measure limit for the vertical angles is ± 3-00. The black figures of the
scales correspond to the positive angles, the red scales – to the negative ones;
– the round level 6 controls setting of the angle measuring device in regard
to the horizon;
– the aiming circle 4 defines the magnetic meridian (North-South)
position;
– the handle 6 releases the scale 7 from fixation and sets any reading on it;
– the handle 9 fixes the location of the sighting device on the seat 0 of the
angle measuring device;
– the screws 8 and 9 fix the aiming circle position during adjusting;
– the handwheel 7 fixes the needle of the aiming circle 4.
.6. The spanner 7 (Figure A.9) is intended for screwing out the ring 2
(Figure A.5) which fixes the cap of the illuminator 6 switch (Figure A.9), for
screwing out the screws 0 (Figure A.3) and 3 mechanisms for direction and
height adjustment and for screwing out the screws 7, 8 (Figure A.4) during
adjusting the aiming circle.
.6.2 The charge unit (Figure A.9) is intended for charging of the accumulators
NLTs-0.9-. When transported, is it put into the bag 8 (Figure A.9).
.6.3 The illuminator 6 is intended for mutual orientation of two observers,
as well as for illumination of the scales 7 and (Figure A.4) and of the needle
of the aiming circle 4.
.6.4 The bushing (Figure A.9) is intended for setting into the sighting
device 3 (Figure A.2) and into the illuminator 6 (Figure A.9) together with the
element ТHL-36 2.
.6.5 The napkin 0 is intended for cleaning external surface of the optical
elements.
.6.6 The soft cover 5 is intended for protection of the sighting device mounted
on the tripod from dust, precipitation and during breaks in operation.
