Single photon detection

Single photon detection and imaging

Single photon counting and imaging are techniques used to detect, measure and visualize extremely weak light signals, down to single photons. Photonis single photon detectors are  used in a range of applications, such as High end LIDAR, Quantum optics and Quantum telecommunication, High energy physics, Particle physics, Nuclear physics, Fluorescence imaging, Astronomy, Plasma research and others. To detect single photon signals, Photonis proposes various types of high-sensitivity, fast-timing, low-noise, vacuum tube-based single photon detectors for OEM and end-user applications. Our team of experts provide support and consulting services to help select and implement the right single photon detector for applications such as space based High end LIDAR and others.

Photonis multialkali Hi-QE photocathode technology combines a high quantum efficiency (QE) in the 120-1050 nm spectral range, with a dark count rate as low as 50 Hz/cm², thereby achieving a superb signal to noise ratio. When the photocathode is utilized as an ultra-fast electro-optical shutter, sub nanosecond (billionth of a second) gating speeds can be achieved for accurate transient phenomena imaging.

Photonis single photon detectors are based on patented high end microchannel plate (MCP) technology offering a high dynamic range and an unmatched collection efficiency of >95%.
