DESCRIPTION AND DATA
2.1 SYSTEM DESCRIPTION
The Armasight Eagle is a high-tech, tough and durable binoculars that delivers great
performance. Packed with features, the Eagle is a unit that is equally at home with the hunter as it is
with the professional security officer or law enforcement professional.
The Armasight Eagle can be equipped with high-performance Gen 2+ and Gen 3 IITs including Green
phosphor or Armasight’s “Quick Silver” and “Ghost” IITs, which provide users with natural B&W night
vision displays.
The Eagle utilizes the principle of intensification of the residual light that is reflected from the surround-
ing objects. The optical system of the unit consists of the two objective lenses, the two intensifier tubes
(IT), and the two eyepieces.
The Eagle automatic brightness adjustment system retains the same gain (image brightness), even un-
der unsteady light conditions.
The Eagle 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.
The Eagle features bright light shut-off circuitry and a spot/flood built-in IR illuminator. A built-in IR
illuminator makes it possible to use the unit in low light or total darkness.
The Eagle uses LED lights to indicate illumination level, low battery, and to show the user that the IR
illuminator is on.
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.
