1. BRIEF DESCRIPTION
1.1. Overview
NVS 22-2XT is a night vision attachment to a daytime weapon scope
designed for precise aiming in darkness.
The device is equipped with a high-quality electro-optical image
intensifier tube that amplifies light in the visible and IR spectrum
providing for up to a 400-700 m effective observation range at low light.
Observation range depends on the characteristics of the day scope NVS
22-2XT is attached to and actual observation conditions, such as
available light, atmosphere transparency and target reflectivity. The
observation range increases by brighter light, at moon night, or if the
object is positioned against a light background, such as snow or grass.
The range decreases at lower light, low atmosphere transparency, or if
the object is positioned against dark background, such as plough-land,
desert, stems of trees, etc.
