Newcon Optik NVS-7-3XT Gen 3 Night Vision Biocular

The NVS 7-3 XT from Newcon Optik is a night vision biocular - its optical design incorporates two oculars, one objective, and a single intensifier tube. Dual-eye viewing provides comfort during extended viewing periods, while enhancing the level of depth perception within the scene. This low-light optic is configured with a high-performance system that features a high-quality 3rd generation XT intensifier tube that delivers a remarkable 57-64 lp/mm of resolution

The NVS 7 can be used hand-held, or fitted to a head or helmet mount for hands-free operation. Both oculars are fitted with a soft rubber eye cup; this provides moderate protection against bumps, and it also minimizes the amount of light that can reflect onto the operators face. This NVS 7 also features in-view low-battery and IR-on indicators.

There are many variables that affect the distance that one can see with a night vision device; the object's size, ambient weather and lighting conditions, the level of detail needed for recognition, etc. The important factors to consider when evaluating any night vision device are the generation of the intensifier tube along with its specified resolution and s/n ratio. The magnification, clarity, and light transmission performance of the NVD's optics also contribute to its low/no-light performance capabilities.
