The SPCM-AQRH-16 is a self-contained photon counting module that utilizes a unique silicon avalanche photodiode (SLiK) with a circular active area. It achieves a peak photon detection efficiency of 65% at 650nm. The module is thermoelectrically cooled and temperature-controlled to ensure stabilized performance. It generates a TTL-level pulse for each photon detected, featuring a 25 cps maximum dark count rate and a typical dead time of 22-25 ns.
Temp Range5 to 70°C
Voltage5VDC
