Semiconductor photomultiplier detector
The semiconductor photomultiplier detector module uses Geiger-mode semiconductor photomultipliers to detect single photons and perform room-temperature photon-number resolution and counting. Components include a multipixel photon counter, high-speed amplification, high-voltage circuitry and signal readout. The counter provides excellent room-temperature number resolution, a broad photon-flux dynamic range and nanosecond response. Applications include fluorescence, nuclear-radiation detection, astronomy, biomedicine, laser ranging and quantum information, particularly short-pulse weak-light detection and photon-number resolution.
