The PMA Hybrid is a compact single photon sensitive detector based on a fast GaAsP Hybrid Photomultiplier Tube with peltier cooler to reduce the dark count rate. The detector includes a high voltage power supply and pre-amplifier with overload protection and emergency shut down procedure if the APD current is too high. Overload protection, high voltage setup and temperature regulation are calibrated at PicoQuant and do not require any adjustment. The detector is prepared for PicoQuant system integration via CAN interface.
The PMA Hybrid features a very high photon detection efficiency up to 45 % at 500 nm and is sensitive in the wavelength range between 300 nm and 700 nm. It is built in a nickel coated aluminum housing to achieve high level of RF and magnetic shielding and protection against the interference with other devices. The built-in pre-amplifier is specially targeted at timing sensitive applications such as Time-Correlated Single Photon Counting (TCSPC).
