Feature of Cooled Continuous Zoom LWIR Lens:
In recent years, zoom objective lenses have been widely used in many fields. The wavelength range of commonly used infrared radiation (medium wave 3um-5um and long wave 8-12um) is 10 to 20 times that of the visible wavelength (0.37um-0.78um), which means that the resolution of the infrared system is ten to twenty times that of visible light one-third.
There are only a few materials that can transmit infrared wavelengths: silicon, germanium, zinc selenide, zinc sulfide, calcium fluoride, and magnesium fluoride.
Medium-wave cooled continuous zoom infrared optical lens with wavelength 3.7-4.8um, focal length range 18-275mm, aperture 5.5, AR outer coating, large field of view imaging range 1m~∞, small field of view imaging range: 30m~∞, suitable for 640x512 specifications Wave Cooling Detector. Due to the wide range of operating temperatures of handheld devices, the medium-wave cooling continuous zoom lens can be used in the working environment of -40°C~+60°C, and has a wide range of uses.
