Cooled Photodiode Extended InGaAs 1.2 – 2.6 µm
The CPOD serials cooled extended InGaAs photodiode provides ultra-low noise for detecting near-infrared light in the 1.2-2.6 µm range. These detectors are hermetically sealed to ensure longevity. Within the detector package, a thermoelectric cooler is integrated with options of 1, 2, and 3 stages, as well as integration with a MEMS chopper, significantly reducing background noise while maintaining a compact format. Additionally, a driving PCB with an amplifier is available for convenient use.
