DESCRIPTION AND DATA

2.1 SYSTEM DESCRIPTION

The Nyx7-4.5x PRO is a hand-held night vision system that allows the user to operate it while conduct-

ing long-range surveillance in both moonlight and starlight conditions.
The Nyx7-4.5x PRO utilizes the principle of intensification of the residual light that is reflected from the

surrounding objects. The optical system of the unit consists of an objective lens, an intensifier tube (IT),

and two eyepieces.
The Nyx7-4.5x PRO automatic brightness adjustment system retains the same gain (image brightness),

even under unsteady light conditions.
The Nyx7-4.5x PRO automatic protective system controls illumination through a photoreceiver. If the

illumination level surpasses 100-300 lx for more than 10s, the unit will shut off automatically.
A built-in IR illuminator makes it possible to use the unit in low light or total darkness.
The Nyx7-4.5x PRO uses LED lights to indicate illumination level, low battery, and to show the user that

the IR illuminator is on.
Additionally, the Nyx7-4.5x PRO MG version incorporates gain control, which allows the user to increase

or decrease the brightness of the image to compensate for overly bright or extremely dark conditions.

NOTE:

The equipment requires some light (moonlight, starlight, etc.) to operate. Performance of the

device depends upon the level of ambient light in the environment. Please remember the fol-

lowing:
— The level of ambient light in the environment is reduced by the presence of clouds, shade,

or objects that block natural light (trees, buildings, etc.).
— The equipment is less effective when operated in shadows and other darkened areas.
— The equipment is less effective when operated in rain, fog, sleet, snow, or smoke.
— Under starlight conditions, particularly in low-contrast environments such as snow-cov-

ered territory, sandy deserts, large bodies of water or grassy hills, the visibility may degrade,

thereby disguising or masking changes in terrain.
— The equipment will not “see” through dense smoke.
