SAP500-Series

Photodiode by Laser Components

Note: Your Quotation Request will be directed to Laser Components.

The SAP500-Series from Laser Components is based on a “reach-through” structure for excellent quantum efficiency, extremely low noise and bulk dark current and high gain. This APD, which has an active area of D = 500 µm, can be used in either normal linear mode at gains of up to 250 or greater, or in the “Geiger” mode. The Geiger Mode APD can be biased above the breakdown voltage to allow detection of single photons.

The SAP500-Series can be used in a variety of demanding applications including LIDAR, spectroscopy, small-signal fluorescence detection, and photon counting. The APD is hermetically sealed in a modified TO-46 package, or as an option, it can be supplied with a one stage TEC in a TO-37 package or with a two-stage TEC in a TO-8 package.
