Photon Counting Detectors and Instruments

Download PDF

Voxtel’s series of single photon sensing products include single photon photomultipliers (SiPMs), Geiger mode InGaAs APD detector and photon counting modules. These feature high detection efficiencies, low false alarm rates, and high-channel count time-to-digital conversion (TDC), binary pulse processing (BPP), and time event processing. The line of single photon sensitive detectors and single photon counting (SPC) instruments are ideal for applications including scanned LADAR, LIDAR, Positron Emission Tomography  (PET),  time-correlated single photon counting (TCSPC), and nuclear and high energy physics (HEP) experiments.
