ATN Mars Night Vision Weapon scopes - the world’s largest line of professional Night Vision sights – has a new flagship – the ATN MARS X4. Inspired by ATN’s quest for technical perfection and named after the Roman God of War, the ATN MARS NV riflescopes represent the absolute latest in the world of Night Vision equipment. Similar to all ATN Aries scopes the ATN MARS features only the purest grades of heavy glass and computer-aided optical designs to create multi-element, high-speed, multi-coated lenses for ultra-fast light transmission and resolution beyond current military standards. All optical lenses on the MARS scopes are individually fitted and calibrated to achieve optimum performance. In ATNs continuing effort to supply our clients with cutting edge Night Vision solutions we are proud to introduce a new line of select units based on ATN White Phosphor Technology© (WPT©). 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. 7 out of 10 users name WPT© as a "Night Vision Preference" when compared with common green night vision, especially in an urban environment. "No lab testing needed on WPT© - the depth perception is phenomenal and noticeably better than what I used in the past." - SOF Operator K. Designed for Special Ops WPT© is not a toy. If your life depends on your gear and you want to improve your operational effectiveness you should check it out. ATN WPT© represents a new standard for night vision.
