Mid Infrared Detector 2 – 5 µm
The CPOD serials lead selenide detectors (PbSs) provide enhanced sensitivity for detecting mid-infrared light in the 2-5 µm range. These detectors are hermetically sealed to ensure low leakage. Within the detector package, a thermoelectric cooler and a MEMS chopper are integrated, significantly reducing background noise while maintaining a compact format. Additionally, a driving PCB with an amplifier is available for convenient use. All stock detectors undergo a minimum four-week aging period. Experience with detectors manufactured through our proprietary process, which includes the aforementioned aging period, has shown the electrical characteristics to remain stable to within 10% for over a year. The typical response for PbSe detectors operates in the 0.5 to 3 micron spectral region with time constants below 400 μsec.
