High dynamic range photodetector
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.
