InAsSb photovoltaic detector P12691-201 High-speed response and high sensitivity in the 8 μm spectral band Thermoelectrically cooled infrared detector with no liquid nitrogen required The P12691-201 is an infrared detector that provides high sensitivity in the 8 μm spectral band by employing our unique crystal growth technology and back-illuminated structure and by 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 P12691-201 is easy to use as it uses a compact package (TO-8) not requiring liquid nitrogen. Features Applications High-speed response Gas analysis High sensitivity Radiation thermometers High reliability Thermal imaging Compact, thermoelectrically cooled TO-8 package Remote sensing RoHS compliant FTIR Can be assembled in a module with QCL Spectrophotometers Options (sold separately) Heatsink for two-stage TE-cooled type A3179-01 Temperature controller C1103-04 Infrared detector module with preamp (custom order product) Structure Parameter Window material Package Cooling Photosensitive area Specification Ge with AR coating TO-8 Two-stage TE cooler ϕ1.0 Unit mm Value 0.2 1 0.1 -40 to +60 -55 to +60 Unit mW A V °C °C Absolute maximum ratings Parameter Thermistor power dissipation TE-cooler allowable current Reverse voltage Operating temperature Storage temperature Symbol Pd_th ITE max.
