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 (SPCMs) – 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.
