The MilSight T90 TaNS Gen 3 NV Weapon Sight from FLIR is a night vision device used to transform a day optic into a low-light targeting system. FLIR's Tactical Night Sight (TaNS) fuses a weather-sealed housing with a Gen 3 image intensifier and a fast 50mm f/0.9 lens system, making this clip-on optic ready for reliable performance in almost any battlefield condition. The T90 can be focused as close as 10 ft and has a built-in infrared illuminator.
The T90's catadioptric optical design equips the sight with f/0.9 light gathering ability and minimizes the footprint of the housing, making this lens system both portable and bright. Optimized for day scopes with magnification between 1x and 8x, the T90-day scope combination is well-suited for close to mid-range targets. An integrated quick-release mount allows the T90 TaNS to mount in front of the day scope by clamping to a Picatinny rail using a throw-lever lock. FLIR's Shock Mitigation System and Permanent Boresight Alignment allow the T90 to hold zero even after sustained recoil from heavy caliber firearms.
FLIR's proprietary Modular Utilitarian Power Pack System (MUPPS) is an interchangeable power supply that allows the operator to replace the power pack quickly—without fumbling around with loose batteries or aligning the polarity of the battery cells. The MUPPS power pack accepts AA or CR123 battery cells, and it has a temperature-compensated circuit that helps the T90 accurately determine the remaining battery life even in cold temperature.
In addition to the durable housing and high-performance imaging system, the T90 weapon sight features a range of user-friendly functions that can provide the operator with a tactical advantage in the field. The T90 has a simple, menu-free interface that make each of the device funtions immediately available. The MilSight T90 comes with a MUPPS power pack, and the weapon sight is backed by FLIR's their 2-year warranty.
