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 50ns per channel. An outstanding timing resolution of less than 60ps 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 +5V and -25V are needed for operation in photon counting mode. The ID150 exhibits no crosstalk and is not effected by strong illumination.


  • Peak photon detection at 500nm
  • Reliability of CMOS technology
  • Compact in TO header
  • Low bias voltages (+5V and -25V)
  • Fast Active Quenching Circuit
