The Vulkan 640 Thermal Biocular with 75mm Germanium Objective from Night Optics gives you the ability to observe heat sources of various origins during day or night. This long-wave infrared handheld thermal imager features a 640X480 VOx sensor with spectral range of 7-14 μm and sensitivity of 50mK. The optical system consist of 75mm focal length germanium lens system and offers 1x optical magnification, up to 4x digital zoom, and 9-12º angular field of view. The 800x600 dual OLED display has a refresh rate of 30 Hz and an output with different polarity modes: white hot, black hot, and sepia. A video-out port enables the use of optional external recording in PAL or NTSC format. Thermal imaging is extremely difficult to detect with other devices because they are passive and emit no energy, unlike laser targeting or near-infrared illumination used with NVDs.
Additionally, the Vulkan thermal biocular features water resistant housing, wide rim closed type eyecups for additional light insulation, a diopter and interpupillary adjustment. Also included with the main unit, are a soft case, a lanyard, a shoulder strap, a lens cleaning pad, a video cable, an external power cable, and three CR-123 batteries.
