Studies show that nighttime scenes appear remarkably more natural in black and white versus the usual green. B&W provides clearer information about contrast, shapes and shadows. ATNs White Phosphor Technology provides users with this natural B&W night vision image. Operators that tested units that use ATN WPT reported a significantly better degree of detail, overall contrast, full moon similarity and range of shades. WPT provides more discriminating shades of intensity between white and black than between green and black resulting in better contrast and depth perception then when compared to green phosphor NVG's. The majority of the WPT performance characteristics are on par or better then the latest Gallium Arsenide based image intensifier tubes. WPT specifications include typical resolution of 68lp/mm (with some over 74lp/mm) and Signal-to-Noise figures as high as 25.
