Photodiodes
Cooled Photodiode InGaAs 0.85 – 1.7 µm
The CPOD series cooled InGaAs photodiode provides ultra-low noise for detecting near-infrared light in the 0.85- 1.7 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. Due to their high sensitivity to electrostatic discharge, warranty coverage applies only to fully metal covered modules the benchtops, which include proper protection. Other versions of the lasers and photodetectors are not covered by any warranty. Please use them with great caution.
