Mid Infrared Detector 2 - 5 µm

SKU: MIRD

The MIRD 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. TE-cooled packages are also available with a response in the 2 to 5 micron region, featuring increased D*.
A typical spectral response of a standard PbSe detector is depicted below.
