DESCRIPTION AND DATA
2.1 SYSTEM DESCRIPTION
The Nyx-7 PRO is a hand-held, head-mounted or helmet-mounted night vision system that allows the
user to operate it while walking, conducting short-range surveillance, reading maps, conducting ve-
hicle maintenance, or administering first aid in both moonlight and starlight conditions.
The Nyx-7 PRO utilizes the principle of intensification of the residual light that is reflected from the sur-
rounding objects. The optical system of the unit consists of an objective lens, an intensifier tube (IT),
and two eyepieces.
The Nyx-7 PRO automatic brightness adjustment system retains the same gain (image brightness), even
under unsteady light conditions.
The Nyx-7 PRO automatic protective system controls illumination through a photoreceiver. If the illumi-
nation 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 Nyx-7 PRO uses LED lights to indicate illumination level, low battery, and to show the user that the
IR illuminator is on.
The Nyx-7 PRO allows for vertical and fore-and-aft adjustment when mounted to the user’s head or
helmet, when focusing the lens, and when focusing the eyepiece.
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.
