DESCRIPTION AND DATA
2.1 SYSTEM DESCRIPTION
The NYX-14 is a hand-held, head-mounted, helmet-mounted, or weapon-mounted night vision system
that allows the user to operate it while walking, firing weapons, conducting short-range surveillance,
reading maps, conducting vehicle maintenance, or administering first aid in both moonlight and star-
light conditions.
The NYX-14 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 an eyepiece.
The NYX-14 automatic brightness adjustment system retains the same gain (image brightness), even
under unsteady light conditions.
The NYX-14 automatic protective system controls illumination through a photoreceiver. If the illumina-
tion level surpasses 100-300 lx for more than 10 s, 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-14 uses LED lights to indicate illumination level, low battery, and to show the user that the IR
illuminator is on.
The NYX-14 allows for vertical and fore-and-aft adjustment when mounted to the user’s head or hel-
met, when focusing the lens, and when focusing the eyepiece.
Additionally, the Nyx-14 MG version incorporates gain control, which allows the user to increase or de-
crease 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.
