The SPCM-AQRH-13-FC is a self-contained photon counting module that utilizes a unique silicon avalanche photodiode (SLiK) with a circular active area of 180 µm. This module detects single photons over the wavelength range of 400 nm to 1064 nm, achieving peak photon detection efficiency of 70% at 650 nm. It features electronic circuit enhancements that reduce dead time to less than 25 ns and includes an integrated FC fiber connectivity option. The diode is thermoelectrically cooled and temperature controlled to ensure performance stability despite ambient temperature changes.
