4. ASSEMBLY
The binoculars appearance is shown on the Figure 1. It consists of the binocular itself,
U-mount and tripod.
4.1 Basic Optical Train
The optical train of the device is a telescopic system which consists of two branches.
Each branch has an objective composed of lenses I, 2 (Fig. 1) and prism 3, 4, 14, an
eyepiece composed of lenses 5, 6 and cemented lenses 7, 8, 9, changeable light filters
10, 11.
The light beams which come from the object to be viewed pass through the objective,
and after collecting in its focal plane from an inverted image of the object.
There is a prismatic inversion system composed of prisms 3, 4, 14 in the focal plane
of the eyepiece for obtaining an erect image. The prisms serve also for deviation of the
sighting line by 30 upwards and for changing the distance between the exit pupils and
between the entrance pupils.
Reticle 13 which is a plane - parallel plate is positioned in the focal plane of the right
objective. The plate is engraved with three scales: vertical, horizontal and angle -
measuring once. The field of view is shown in Fig. 7.
The vertical and horizontal scales are intended for measuring the angular dimensions of
the objects. The division value is 0-05. The total range of the vertical scale is 0-30 and
horizontal one is ± 0-30. The central sign (cross-hairs) indicates a centre of the field of
view. Light filters 9, 10 (Fig.8) facilitate the condition observation.
4.2 Design of the device
The device consists of two telescopes, casings 2 and 4 (fig. 2) which are connected
below by means of a mechanism of the eye distance with handwheel 5 (Fig.5).
Each telescope consists of a casing, objective 3 (Fig. 4), block of prisms 9, eyepiece,
desiccator 10,valve 12 and blind.
The eyepieces are set for the image sharpness of the target by an observer’s eye by
rotation of scales 1 (Fig.3). The value of the diopter setting of the eyepieces (in the
range from minus 3 to 5 diopters) is determined by scale 1 (Fig. 3) and indices on
casings 2 and 6. In operation with the device, if it is necessary, changeable light filters
9, 10 (Fig. 8) of a required colour from the single STA kit are put on.
Headrest 8 (Fig. 4) is inserted in bracket 6 fastened on casing 2 (Fig. 2). The headrest
serves as a support for the head and ensures a convenient operation. It can be moved
and to be fixed with the use of handle 7 (Fig.4).
Desiccators 10 (Fig.4) to be filled with silica gel are fastened on casings 2 and 4 (Fig.
2) and serve for constant desiccation of the device inner cavity.
Blinds 3 and 5 (Fig. 2) are put on casings 2 and 4 on the side of the objectives, protect

7
them against lighting by the sunrays and serve for decreasing detrimental (diffused)
light, which penetrates in the device.
The tripod (Fig.6) is designed for mounting the device on this ground or any
immovable base.
The mechanism of the vertical laying consists of outer bracket, its box embodies
gearing train, gears and limb with the scale of angles of elevation. The mechanism of
horizontal 6 laying performs horizontal laying of the device with the help of handles
which are also used for vertical laying.
The round spherical level 6 (Fig. 2) serves for levelling the device.
It consists of vial and casing. The vial is filled with ethyl alcohol. Three concentric
circumferences are marked on its outer surface; they are used for determination of the
device levelling accuracy. The level division value is 0-02.

5. GENERAL DIRECTIONS
For faultless operation of the device it is necessary to keep to the following:
- protect the device against impacts and damages;
- avoid touching the optical surfaces with hands and oiled cleaning cloth;
- remove systematically dust, dirt and moisture from the optical surfaces with the use
of clean napkin or brush from the single STA kit;
- replace the desiccators in due time;
- avoid exerting excessive effort in rotation of the handwheels and handles.
In operation with the device in the fields one should use cover 14 (Fig. 8).
Depending on the concrete conditions of operation one uses for mounting the device
the following supports:
- the stand;
- the tripod (Fig. 6).
6. CONTAINERS AND PACKING
Housing is designed for carrying and transportation of the device and single STA kit.
Prior to packing the device one obtains the minimal interpupillary distance between the
eyepieces by using handwheel 5 (Fig.5).
Remove the device from the tripod or stand depending on the kind of mounting.
Put the device in the housing on the blocks and press it with a cleat.
The parts of the single STA kit are put at the place in compliance with list of enclosure
available on the inner side of the housing cover.
7. PREPARATION OF THE DEVICE
Prepare the device for operation in the following order:
- remove the protective caps from the objective and eyepieces and wipe the device with
soft cleaning cloth and the outer optical surfaces with a napkin, if it is necessary;
- obtain a sharp image of both tubes of the device in turn for each eye by rotating scale
1 (Fig. 3) (in doing so in turn close the eyes or darken the inlet posts of the device);
- set the eyepieces at the distance equal to the interpupillary distance of the observer.
To perform this one obtains a clear visibility of the full field of view of the reticle (the
field of view is shown in Fig.5) and viewing through the device with both eyes. The
device field of view must be visible in the shape of one whole circle without cutting the
edges.

8. ORDER OF OPERATION
Operation with the device in the following way:
- put one of light filters from the single STA kit in the device. If it is necessary (fit the
light filter mount at the places of its cutting for its reliable fastening on the eyepieces);
- move out the blinds;
- reliable the brake of laying for direction by rotation of handwheel and carry out an
observations.
9. DERANCEMENT AND METHODS OF ELIMINATION
Derangement, outer
display and additional
signs
Probable Cause Method of elimination
The terrain image is visible
weakly through the device
Dust and dirty on the outer
surfaces of the optical
pieces
Sweating of the optical
pieces
Wipe the outer optical
pieces by using the single
STA kit
Silica Gel in the
desiccators becomes pink
Silica gel is saturated with
moisture
Replace the desiccator with
a new one from the single
STA kit
The level bubble is not
visible or it is increased
