1. BRIEF DESCRIPTION
The AN series of daytime binoculars includes
AN 8x30,
AN 7x50MC,
AN 7x50M22,
AN 10x50M22.
Though the binoculars differ in optical characteristics and
some features, they all share a similar optical and
mechanical design. Unless explicitly mentioned this
manual refers to all models.
The binoculars are designed and manufactured to military
specifications and provide excellent brightness, image
clarity and true image color. The built-in range finding
reticle, M22 standard, enables measurements of horizontal
and vertical angles, as well as calculation of height, width
of the target and distance to the target.
All binoculars are waterproof, shockproof and nitrogen
filled. They are also rubber armoured and have a tripod
socket.

2
The binoculars feature foldable rubber eye cups and long
eye relief to provide for comfort viewing with glasses or
mask. Though many binoculars feature fold down eye
cups, only the ones featuring a long eye relief offer a truly
full view while wearing glasses.
The AN 7x50MC has a built-in compass illuminated
either by ambient light or by an internal light source
powerd with two tablet batteries.
These binoculars meet the standards and requirements of
GJB1240, GJB150 and MIL-STD810.
The user can be confident whether the instrument is used
in the military, security, traffic control, marine, aviation,
or any other application requiring reliable and powerful
optical equipment.

3. DESIGN AND APPEARANCE
3.1 Optical design
Optical design of the binoculars is presented on Fig. 1.
1 – objective lens 2 – erective prisms
3 – reticle lens 4 – eyepiece
AN 7x50MC contains an additional compass projector
that brings light to illuminate the compass scale.
Fig. 1

6
The light from the object or target you are looking at
enters the binoculars through the objective lens system (1,
Fig. 1). Due to the objective lens, the image at this point
is turned upside down. However, as the image passes
through the prism system, (known as the erective prisms)
(2, Fig. 1) it becomes right side up (erect) and changed
from right to left, to left to right. After the prisms the
image rays pass through the reticle lens (3, Fig. 1) and
then through the eyepiece (4, Fig. 1).
3.2 Reticle
Reticle lens (3, Fig. 1) contains vertical and horizontal
lines that constitute an M22 reticle. Though reticle scales
may form a cross or upside down T (Fig. 2, A, B, C) they
share the same scale division value: each small division
on both vertical and horizontal lines is 5 mils and each big
division is 10 mils (360º equals 6400 mils).

7
Reticle may have an addition scale composed of two lines
(B, Fig.2).

AN 7x50MC is shown as an example. Though all
binoculars have similar design, only MC model has a
built-in illuminated compass.

6. OPERATION INSTRUCTIONS
6.1 Interpupillary distance adjustment
Prior to use you may like to adjust the binoculars to the
distance between your eyes (interpupillary distance).
Holding the binoculars in both hands rotate its halves
until you see one round image.
Note: The image may not be clear at this step. You will
focus it in the next step.
6.2 Focusing the binoculars
The binoculars may have central or independent focus.
Central focus
To focus the binoculars raise the instrument to your eyes
and close your right eye. With your left eye open focus
the image by rotating the central focus adjustment ring
located in front of eyepieces. Use eyepiece focus
adjustment ring to focus image for the right eye if
necessary.
Independent focus
To focus the binoculars raise the instrument to your eyes
and close your right eye. With your left eye open focus

12
the image by rotating eyepiece adjustment ring of the left
eyepiece. Repeat the procedure for the other eye.
Note: You may like to remember your dioptre settings to
set them every time you use the binoculars.
6.3 Measuring horizontal angle using the reticle
An M22 reticle built into these binoculars enables
measuring height, distance and size of a target, as well as
angle between two close targets. Though reticle
appearance may differ from one model to another as
described in 3.2, the description below is valid for all
models.
When the angle between two targets is smaller than the
angle measuring range (100 mils), aim the scale line at
one end of the reticle at the target then read the value of
the scale at which another target was located on the
reticle. As shown in Fig. 4, the horizontal angle of
the target (tank) is 20 mils.

13
When the angle between two targets is larger than the
angle measuring range (100 mils), it can be measured in
several steps.
The horizontal angle of cruiser shown in Fig. 5, is 130
mils (60+70=130).
6.4 Measuring vertical angle using the reticle
Fig. 4.
Fig. 5.

14
Vertical angle measurement is similar to horizontal angle
measuring.
When height of the target is smaller than the reticle scale,
its height can be obtained in one measurement.
The height of the beacon, shown in Fig. 6, is 65 mils.
For targets taller than the reticle scale, perform
measurement in steps in the same way as it is described
for the horizontal angle measurement.
Fig. 6.

15
6.5 Using the reticle to calculate distance
To determine the distance to the target use the formula:
D = H/K,
where
D – distance to target in km,
H – estimated height of the target in m,
K – vertical angle of the target in mil.
First, estimate the height (or width) of the target, then
measure target’s horizontal (vertical) angle and calculate
the distance.
For example:
Assuming an image of an adult human figure has a
vertical angle of 10 mils and its height is 1.70m we can
calculate the distance to it:
L=H/K=1.7/10=0.170 (km) = 170 (m)
6.6 Measuring distance directly using the reticle
If reticle of your binoculars has an additional scale shown
at Fig.7 distance to a target may be measured directly.

16
Place the lower edge of the target at the horizontal line on
the reticle. The reading of the scale at the point where
target’s 2 m level touches the scale is the distance in
meters.
Assuming that vehicle on the Fig. 7 is 2 m high; the
distance to it is 550m.
Fig. 7

6.7 Calculating target's size using angle readings
To calculate height and width user will need to estimate
the distance to the target and measure its horizontal and
vertical angles. Then using the formula for distance
measurement one can calculate target’s height:
H=DxK,
where K is vertical angle in mils,
D is distance in meters and
H is height in meters.
For example: if distance to the target is 0.6 km and its
horizontal angle is 30 mils and its vertical angle is 60
mils, using the formula you can calculate:
The height: H=0.6 x 30= 18 m
The width: W=0.6 x 60=36 m
