The MilSight™ T90 TaNS® (Tactical Night Sight®) is a high-resolution clip-on night vision device (CNVD) that mounts on any MIL-STD-1913 rail interface forward of an existing scope, adding night vision capabilities to daytime target acquisition platforms. The MilSight T90 TaNS utilizes a Gen 3 1200 FOM image intensifier tube, a fast f/0.9 catadioptric lens for a brighter and sharper image in starlight, and patented permanent boresight alignment technology. The unit is installed, operated, and removed without tools and without affecting boresight (permanent boresight alignment). The unit can be mounted on a spotting scope for long range reconnaissance, hand-held as a Night Observation Device (NOD), or used in other night-time operations requiring night vision capabilities. The MilSight T90 TaNS features the proprietary and patent-applied-for Modular Utilitarian Power-Pack System™ (MUPPS™), a detachable, field-replaceable battery compartment that accommodates either AA or CR123 batteries. Also standard on MilSight T90 TaNS is a temperature-compensated low-battery indicator that appears intermittently in the operator’s field of vision (when approximately 30 minutes of battery service remains), but does not obstruct or otherwise interfere with the target image.
