Indium Antimonide (InSb) is a crystalline compound of indium (In) and antimony (Sb), boasting stable physicochemical properties and excellent process compatibility. As a III-V narrow-bandgap semiconductor, it’s ideal for infrared detectors-used in thermal imagers, FLIR systems, infrared-guided missile systems, and infrared astronomy-with sensitivity to 1-5μm wavelengths. It was widely applied in legacy single-detector mechanical scanning thermal imaging systems and also serves as a terahertz radiation source (a strong photo-Dember emitter). Available in 2 3 4 sizes.
