InAsSb photovoltaic detector



High-speed response and high sensitivity in the 5 μm spectral band Thermoelectrically cooled infrared detector with no liquid nitrogen required

The P11120-201 is an infrared detector that provides high sensitivity in the 5 μm spectral band due to our unique crystal growth technology. The InAsSb photovoltaic detector has a PN junction that ensures high-speed response and high reliability. Typical applications include gas analysis such as CO2, SOx, CO and NOx. Unlike the P11120-901 metal dewar type detector, the P11120-201 is easy to use as it uses a compact package (TO-8) not requiring liquid nitrogen.

-High-speed response
-High sensitivity
-High reliability
-Compact, thermoelectrically cooled TO-8 package
-RoHS compliant
