Single Photon Counting Modules from Excelitas Technologies achieve excellent performance in very low light level applications
SPCMs – Single Photon Counting Modules – detect single photons of light over the 400-1060nm wavelength range – a range and sensitivity that often outperforms a photomultiplier tube. A key strength is the peak photon detection efficiency of up to 80% @ 700nm, with selections for various wavelengths available.
The active area of 180µm is the largest on the market, with uniformity that is simply unmatched. SPCMs have extremely high single-photon detection efficiency, and are much more sensitive than the PMT in the visible range.
Single Photon Counting Modules – Applications
Typical applications for these single photon detectors include LIDAR, Photon-Correlation Spectroscopy, Astronomical Observation, Optical Range Finding, Adaptive Optics, Ultra-Sensitive Fluorescence, Particle Sizing and Quantum Communication.
The SPCM-AQ4C is a four-channel photon counting module capable of detecting single photons of light over the wavelength range from 400 nm to 1060 nm. Each channel is independent from the others.
The newly enhanced SPCM-AQRH Single-Photon Counting Module detects single photons over the wavelength range of 400 nm to 1064 nm with performance parameters superior to other solid state or vacuum-tube based photon counters.
