Binoculars or field glasses are two refracting telescopes mounted side-by-side and aligned to point in the same direction, allowing the viewer to use both eyes (binocular vision) when viewing distant objects. Most binoculars are sized to be held using both hands, although sizes vary widely from opera glasses to large pedestal-mounted military ...
The device enhances ambient visible light and converts near-infrared light into visible light which can then be seen by humans; this is known as I 2 (image intensification). By comparison, viewing of infrared thermal radiation is referred to as thermal imaging and operates in a different section of the infrared spectrum.
Active infrared night-vision combines infrared illumination of spectral range 700–1,000 nm (just over the visible spectrum of the human eye) with CCD cameras sensitive to this light. The resulting scene, which is apparently dark to a human observer, appears as a monochrome image on a normal display device. [ 13 ]
Binocular rangefinder with day optics, an integrated 3-dimensional 360° digital compass and a class 1 eye-safe laser rangefinder. Allows infantrymen and forward observers to conduct long-range observation and target acquisition missions from 5 m to over 4 km, at both day and night. Mostly replaced by the Safran Vector 21
The AN/PSQ-42 Enhanced Night Vision Goggle-Binocular (ENVG-B) is a third-generation passive binocular night vision device developed for the United States Army by L3Harris.It combines dual tube image-intensifying (I²) and thermal-imaging technologies into a single goggle, enabling vision in low-light conditions.
LUCI (originally LUCIFER: Large Binocular Telescope Near-infrared Spectroscopic Utility with Camera and Integral Field Unit for Extragalactic Research) is the near-infrared instrument for the LBT. [20] [21] [22] The name of the instrument was changed to LUCI in 2012. LUCI operates in the 0.9–2.5 μm spectral range using a 2048 x 2048 element ...
