The product consists of a detector module, which is assembled by flip-chip interconnecting a 4x4 array of InGaAs single-photon avalanche diode (SPAD) chips and a CMOS main passive quenching circuit chip, along with a voltage inverter module, a cooling module, and a signal control module. In Geiger-mode operation, each pixel of the detector component operates independently and freely, detecting weak light signals in the near-infrared wavelength range of 0.95 to 1.65 micrometers and providing real-time output in TTL electrical signals.
