Brand: ThorLabs | Category: Scientific & Laboratory Equipment
Actively quenched, temperature stabilised silicon avalanche photodiode modules that produce a TTL pulse for every detected photon. They pair with correlated photon pair sources for quantum optics teaching, and also suit photon correlation spectroscopy and LIDAR.
