Si APD array S8550-02

Datasheet [563 KB/PDF]

The S8550-02 is an APD (avalanche photodiode) array designed for short wavelength detection, featuring low noise and low terminal capacitance. The S8550-02 also offers uniform gain and small crosstalk between each element.

-High sensitivity and low noise in short wavelength region
-Low terminal capacitance
-Optimized for blue light detection
-Uniform gain and low crosstalk variation between each element
