Infrared Optical Elements Are Made from Special Materials Such as Germanium and Zinc Selenide, Providing Efficient Transmission from Mid-Wave to Far-Infrared Bands
Applications
Thermal imaging/night vision: military sights use chalcogenide lens arrays for fully passive infrared imaging. Firefighting imagers use uncooled infrared windows to identify heat sources through smoke. Border surveillance uses long-wave objectives for all-weather tracking. Industrial monitoring: steel continuous casting uses thermometry windows to monitor solidification temperature fields. Photovoltaic EL inspection uses zinc-selenide prisms and precision optics for micrometer-scale cell hot spots. Petrochemical cracking uses high-temperature windows to monitor reactor heat flow. Environmental/weather monitoring: greenhouse-gas satellites use infrared grating spectrometers to retrieve global carbon-dioxide distributions. Germanium arrays scan square-kilometer fire areas. Infrared reference sources calibrate atmospheric-transmission visibility measurements. Medical diagnostics: breast-cancer screening uses infrared microscope objectives for tissue blood-oxygen metabolism imaging. Noninvasive glucose monitors use ATR prisms for subcutaneous spectra. Laser physiotherapy filters precisely reject out-of-band radiation. Security inspection: airport systems use chalcogenide prism arrays for multispectral hazardous-material recognition. Infrared endoscopes locate insulation-related heat leaks in industrial pipes. Power-inspection drones use infrared polarizing lenses and laser focusing to diagnose high-voltage partial discharge. Frontier research: infrared adaptive optics correct atmospheric turbulence in deep-space observation. Off-axis parabolic mirrors improve molecular-fingerprint sensitivity in quantum-cascade spectroscopy. Radiation-resistant tokamak windows monitor plasma-edge temperature. Transport/autonomous driving: aspheric germanium lens groups improve vehicle night vision in rain/fog. Infrared fill-light filters enable license-plate recognition without light pollution. Infrared fiber sensor heads warn of overheated train bearings.
