INFRARED DETECTOR
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 碌m.
These detectors offer better characteristics than PbSe photoconductive detectors.
