Indium Antimonide (InSb) is a crystalline semiconductor made of antimony and indium. It belongs to the III-V group and is a narrow-gap semiconductor material. Detectors made of indium antimonide are sensitive and lie between a wavelength of 1 and 5 µm. Indium antimonide was commonly used in mechanically scanned single-detector thermal imaging systems.
High-purity and ultra-high-purity Indium Antimonide (InSb) materials are crucial components for the research, development, and production of advanced technologies that require optimum properties, performance, and quality.
