FOG5522Y InGaAs Geiger-mode APD

Avalanche photodiodes (APDs) in Geiger mode to perform photon counting. The gain and noise performance of available linear-mode APDs was too poor to detect the photocurrent pulse from a single photon using existing amplifier technology. Our InGaAs Geiger-mode APD can easy detect the weak signal.It is special Designed specifically for single photon counting applications.

Product Features

● Designed specifically for single photon counting applications

● Using in Geiger mode
