Tech Spec - ATN Night Vision

How Nightvision Works




Originally designed to give soldiers the ability to move and fight in darkness, nightvision now provides outdoor enthusiasts the ability to observe nocturnal animals in the wild. While most nightvision units operate in a similar fashion, they are available in different grades with varying levels of performance.

First Generation – Generation I devices use an image intensifier that consists of a single or three-stage vacuum tube, which amplifies weak input images. Generation I units are capable of producing moderately clear images at relatively close range.

Second Generation – Generation II devices employ microchannel plate intensifiers which offer greater spectral sensitivity than Generation I units, providing you with a clearer, sharper image. Generation II tubes provide satisfactory performance in low-light levels and exhibit low distortion.

White Phosphor Technology™ – With cutting-edge WPT™-nighttime scenes appear remarkably more natural in black and white versus the usual green. ATN WPT™ provides a significantly better degree of detail, overall contrast, full moon similarity, range of shades and depth perception when compared to green phosphor NVG's. Specifications include typical resolution of 68lp/mm (with some over 74lp/mm) and Signal-to-Noise figures as high as 25.


Third Generation – Generation III devices features an improved microchannel plate greatly enhances resolution and tube life.


Fourth Generation – Generation IV devices with gated/filmless technology demonstrate substantial increases in target detection range and resolution, particularly at extremely low-light levels.
