TVS 7B TVS 7B Highly sensitive compact thermal vision goggles enable seeing in darkness by transforming invisible infrared radiation into visible image. Some of the tasks suitable for the instrument: • Search and rescue • Surveillance, counter-terrorist measures • Hunting and animals observation • Industrial research and process control • Inspection of thermal insulations in residential and industrial buildings • Inspection of high voltage transmission linests. This unit has black hot or white hot image polarity. Image may be transferred to an external monitor via circular connector. TVS 7B detects extremely small differences in emperature, so that user can distinguish people from their immediate surroundings. Unlike night vision devices the thermo vision units operate 24 hours a day, in daytime and at night, even in total darkness of enclosed space. Thermo vision scope enables aiming seeing through smoke or fog. Modern uncooled bolometer array and electronic signal processing enables detecting temperature difference bellow 0.1°K.         Specifications Objective lens diameter Focal length Field of view FOV Magnification Lens type Detection range, human Detection range, car Detector Sensor Display resolution Output resolution, format Thermal sensitivity Spectral Response Operating time on one set of batteries Water resistant Battery Dimensions Weight     25 mm 25 mm 11x8 degrees 19 m x14 m @ 100m 1.7x or 3.4x (digital) Germanium 475 m 900 m Amorphous silicon Uncooled Microbolometer 640x480 640x480, NTSC <100 mk 7-14 um up to 5 hours Yes Lithium or rechargeable CR123 or external 157x60x78 mm 450 g
