Intended for large-volume OEM applications, the ID150-1×8 is the only multichannel solid-state single photon detector on the market. It consists of a CMOS silicon chip packaged in a standard TO8-16pin header with a transparent window cap.
The chip combines 8 in-line single photon avalanche diodes that can be accessed simultaneously for parallel processing. A fast active quenching circuit is integrated within each pixel in order to operate each diode in photon counting regime; leading to a dead time of less than 50 ns per channel. An outstanding timing resolution of less than 60 ps allows high accuracy measurements.
The chip is mounted on a printed circuit board on top of a single-stage thermoelectric cooler (TEC). A thermistor can be used to measure the temperature of the chip. Only two low power supplies of +5 V and -25 V are needed for operation in photon counting mode. The ID150 exhibits no crosstalk and is not affected by strong illumination.
