Single Photon Counting Module


Single Photon Counting Module

The SPCM-AQRH Single Photon Counting Module detects single photons over the wavelength range of 400nm to 1060nm with performance parameters superior to other solid state or vacuum-tube based photon counters.

The SPCM-AQRH can achieve peak photon detection efficiency of approximately 70% at 650nm over a 180µm diameter with unmatched uniformity over the full active area. A TTL-level pulse is generated for each photon detected and the signal is available at the BNC connector at the rear of the module. The operating temperature range has been increased and the module (case temperature) will function between 5˚C and 70˚C. Recent electronic circuit improvements have reduced the minimum dead time to less than 25ns, thereby increasing linearity and improving the dynamic range of the module. Timing resolution of the module was also improved significantly. The SPCM-AQRH has internal protection circuitry that protects the avalanche photodiode and the module electronics from damage due to accidental overload from exposure to ambient lighting.
