The infrared telescope makes it possible to observe targets at a distance of 100 to 250 m, depending on the weather conditions and the time of year.
In the general case, the distance of visibility of the targets depends on the power of the infrared headlight and on the electrono-optical characteristics of the infrared telescope (diameter and focal length of the lenses and the sensitivity of the electrono-optical image transducer). The distance of visibility is also affected by the nature of the target, as different targets reflect infrared rays differently.
In combat use, the NSP-2 infrared telescope is mounted on a weapon, the case with the power supply and the low-voltage converter are mounted either on the shooter's belt or placed next to it on the ground, depending on the position of the shooter when firing.
The NSP-2 infrared telescope is connected to the power supply unit with a 1.3 m long cable. When carrying, it is stored in a bag and the power supply block is hung on the shooter's belt. A metal box is used to transport and store the complete NSP-2 infrared telescope.

Principle of activity:
The principle of illumination of the terrain (target) by invisible infrared rays and the transformation of an invisible image into a visible image is taken as the basis of the activity of an infrared telescope.
This activity is solved by means of an infrared floodlight and an electrono-optical telescope.
The targets are illuminated by infrared rays invisible to the human eye, which are emitted by an infrared floodlight. From the observed target, the reflected infrared rays strike the infrared telescope lens. The amount of reflected rays depends on the illumination and the reflection coefficient of the target, as well as on the state of the atmosphere. The lens produces an invisible infrared image of the target on the photocathode of the electron-optical image converter. Infrared rays incident on the photocathode emit electrons from its surface. The amount of electrons emanating from different places of the photocathode is proportional to the energy of the incident infrared rays, i.e. proportional to the illumination and the coefficient of reflection of the different points of the observed target and terrain.
The electron current (electron image) is accelerated by the effect of the electrostatic field generated by the high voltage of the high voltage converter. The electrons are directed by an electrostatic lens (electrostatic field) to the screen of an electron-optical image transducer.
After the electrons hit the screen (on the layer of luminescent substance), their kinetic energy is consumed to excite the screen, which is emitted by visible light. The brightness of each point of the shadow is proportional to the number of electrons incident on it.
The visible image on the screen is observed through the eyepiece of the infrared telescope.
In the general case, the distance of visibility of the targets depends on the power of the infrared headlight and on the electrono-optical characteristics of the infrared telescope (diameter and focal length of the lenses and the sensitivity of the electrono-optical image transducer). The distance of visibility is also affected by the nature of the target, as different targets reflect infrared rays differently.
