1 APPLICATION
Night vision monocular “Helios - 01” (here and after as monocular)
is intended for observation and terrain orientation at night by natural
light of the Moon and stars as well as in conditions of low illumination
intensity and in full darkness.
Monocular is completed with adapters M49x0.75 and M37x0.75,
which are allow to mount a monocular on camera and video camera
and to operate at night.
An eyepiece of monocular has a diopter laying which allows adjusting
it by user’s eye.
Electrical diagram of monocular allow to protect am image converter
from the intensive light at night.If bright lighting gets into the monocular
objective the screen of the image converter goes out for some period
of time.
Design of monocular provides a mechanical safety and protection
from the rain, snow and dust.

5
The monocular can operate at the ambient temperature from minus
40°C to 40°C and relative humidity of maximum 80% at the temperature
of 25°C.
The monocular is not injurious to health. It is not necessary to take
special measures to protect a user.
A present of small spots on the screen have not inuence on operation
of product.

4 DESIGN AND PRINCIPLE OF OPERATION
The monocular is a complex optoelectronics system for individual
use. Its principle of operation is based on conversion (intensication)
of the image of an objects of low brightness into the visible image at
night by natural light of Moon the stars and so on as well as conversion
(intensication) of IR illumination of various objects to be invisible by
eye into the visible one. The user sees a magnied image of object.

9
The monocular consists of an objective lens 3 (Fig.1), eyepiece 10
and body 6. The body 6 contains an image converter and two battery
housings 5.

10
The objective lens has a protected cover 1.
Eyeshield 12 provides a convenient operation and to protect an eye
from damage.
IR illuminator 4 is located on the body 6. The button to be intended
for switching of image converter 8 and switch 9 of the illuminator are
located on the cover of body. When the switch is disposed in red spot,
the product is switched on. Electrical diagram of monocular allows to
protect am image converter from the intensive light at night.If bright
lighting gets into the monocular objective the screen of the image
converter goes out for some period of time.
For convenience the monocular is supplied with a belt 7 and a
carrying bag. The monocular, light lter and two cells are packed into
the carrying bag.
The light lter 2 is intended for checking of operation of product and
observation for various objects at high level of illumination.
Adapter 13 is intended for mounting of camera and video camera on

11
monocular. Monocular is completed with strap 7 and bag.
The design of the product allows using other photoobjectives, which
have an operating length of 45.5 mm and connecting size of M 42x1.

5 PREPARATION FOR OPERATION AND ORDER OF OPERATION
Before operation:
- install the batteries into the battery housing with the polarity order
shown on the covers;
- screw up the covers 5 (Fig.1) into the body 6 to stop.
- remove the protective cover 1 from the objective lens, put a light
lter 2, switch the monocular pressing a button 8;
- make sure of the green luminance of the phosphor screen which is
due to appear not later that in 2 seconds after the monocular has been
switched on.
The monocular can operate without light lter at night.
To use a monocular at night it is necessary to shut a diaphragm
rotating a ring 15 and to switch the monocular pressing a button 8.
The brightness of screen illumination can be adjusted with diaphragm
to be located in objective lens.
- switch the monocular pressing the button 8 keeping up the level of
brightness of screen illumination.
- rotating a ring 11 of eyepiece 10 and ring 14 of objective lens one

13
should achieve a sharp image of object.
At night or in full darkness one should switch IR illuminator 4 with the
use of switch 9.
When the work is over, the batteries are to be removed from the
battery housings, the objective lens is to be covered and the monocular
is to be put into the case.
When using the monocular together with a camera it is necessary
to:
- screw up an eyeshield 12 from eyepiece 10;
- screw an adapter 13 in theeyepiece of monocular (Fig.2);
- open a diaphragm of objective lens;
- connect the camera to monocular as it is shown on gure 3;
- switch a monocular.
Rotating a ring 11 of eyepiece 10 and ring of objective lens of
monocular and camera one should achieve a sharp image of object.

6 MAINTENANCE
The monocular must be kept clean and protected from dust, shocks
and friction of the optical surfaces. A cotton cloth to be wet with puried
alcohol is to be used to clean optical surfaces. It is not recommended
to use other alcoholic substances. In non-working time the monocular
is to be kept in the case.
7 RULES OF STORAGE
The monocular is to be stored in the heated rooms. For long storage
it is recommended to remove batteries from the battery housings and
keep them in the battery pockets of the carrying case.
