InAs photovoltaic detector
,
P8079 series P7163
Infrared detectors with high sensitivity and high-speed response
InAs photovoltaic detectors have high sensitivity and high-speed response in the near infrared region from 1.5 to 3.8 µm.
These detectors offer better characteristics than PbSe photoconductive detectors.
