InAsSb photovoltaic detector


High-speed response and high sensitivity in the 8 μm spectral band, Thermoelectrically cooled infrared detector with no liquid nitrogen required


The P12691-201G is an infrared detector that provides high sensitivity in the 8 μm spectral band by employing our unique crystal growth technology, back-illuminated structure and integrating a lens. The InAsSb photovoltaic detector has a PN junction that ensures high-speed response and high reliability. Typical applications include gas analysis such as NO, NO2, SO2, and H2S. The P12691-201G is easy to use as it uses a compact package (TO-8) not requiring liquid nitrogen.
