1. BRIEF DESCRIPTION
1.1. Overview
NVS-33 is an afocal night vision attachment to a daytime
weapon scope designed for precise aiming in darkness.
The device is equipped with a high-quality generation 3
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
daytime scope NVS-33 is attached to and actual
observation conditions, such as available light,
atmosphere transparency and target reflectivity. The
observation range increases by brighter light, at moony
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.
