Optical Systems Technology's Star-Tron^® MR-135 (135 mm, f/1.6) lens is Optical System Technology's ultra-compact, lightweight, long-range nighttime passive surveillance lens for use with the Gen-II or Gen-III MK-880 series pocketscope, or the AN/PVS-7B goggles.  The MR-135 attaches to the MK-880 Night Vision PocketScope™ or the AN/PVS-7B goggles simply by removing the 1 X objective from the PocketScope™ and screwing the unit onto the lens.  (The AN/PVS-7 attaches to an interface adapter).  The system is either hand-held or it mounts on a tiny tripod or upon any standard tripod-type interface.  It is aimed by hand and viewed from the rear using the PocketScope™ eyepiece.  It is adaptable to video and SLR cameras as well.  The system magnification is 5.1 x when used with the standard 26.5 mm ocular. 

LENS SYSTEM: Optical Systems Technology's Star-Tron^® 135 mm focal length, f/1.6 catadioptric objective lens, is intended for passive night-vision use.  The optical design is a fast f/1.6 in a package with a total length of only 3.5” and a weight of 520 grams.  The design exhibits low chromatic aberration, and provides crisp imagery over its full 450-910 nm (extended blue) operating range.  It is compatible with both 2nd and 3rd generation intensifiers. 

Vacuum and immersion testing were used to refine the sealing and produce a dry-nitrogen-purged lens, environmentally sealed and designed and tested to withstand water immersion to a depth of 3 feet.  Ports are included for the user to purge the lens as well.
