GNV-X night vision goggles
Night vision goggles GNV-X
GNV-X night vision goggles are designed for navigation during maneuvering the terrain, visual observation over various objects, and reading texts and maps in conditions of natural night illumination / twilight, cloudy moonless night /and in absolute darkness.
The goggles can be used during security and rescue operations, hunting, and exploration of the nocturnal wildlife.
GNV-X night vision goggles are optimal for specific tasks, where free hands are required, or in conditions, when such goggles should be used as the night vision binocular. GNV-X is equipped with a special accessory for helmet mounting.
Standard goggles are supplied without additional optics; however, optionally the goggles can be supplied with a range of 1x, 3x, 5x, and 8x interchangeable lens.
The range of application covers both nonprofessional activities (observation, hunting), and professional (security, law enforcement, search operations).
The device is equipped with electro-optical converters (IIT), the IIT 2+, and IIT 3 generation, which provide green of black&white visible band.
Optionally, goggles can be equipped with a switched power supply.
