Cooled Photodiode Si APD 0.4–1.1 µm

SKU: CSAD

The CSAD serials cooled Silicon APD photodiode provides high sensitivity with gain for detecting from UV to near-infrared light in the 0.4-1.1 µm range. These detectors are hermetically sealed to ensure longevity. Within the detector package, a thermoelectric cooler is integrated with a 3-stage deep cooling as well as integration with a MEMS chopper, significantly reducing background noise while maintaining a compact format. A thermistor is also included in the package to sense the Si photodiode chip temperature for stable operation. It is designed for low-light-level detection applications. Additionally, we offer driving PCB consists a precision TEC temperature controller, an amplifier, and a detector heat sink for convenient use.
