High dynamic range photodetector

PD10S - High dynamic range photodetector
PD10S - High dynamic range photodetector PD10S - Frequency response PD10S - Shot noise PD10S - Noise Equivalent Power

Koheron PD10S is a photodetector with 5 kV/A transimpedance gain and 50 MHz bandwidth. With a noise-equivalent power spectral density below 2 pW / √Hz at 1 MHz, and up to 8 V DC output voltage, the PD10S is a good alternative to the PD100-DC photodetector for high dynamic range applications such as power stabilization of CW lasers.
