950-1650nm InGaAs Single-Photon Array Detector component

The MP6514S detector module consists of 4x4 arrayed InGaAs Single-Photon Avalanche Diodes (SPADs), which are interconnected with CMOS main and passive quenching circuit chips. It also includes a voltage inverter module, a cooling module, and a signal control module. In Geiger mode, each pixel of the detector operates independently, detecting weak light signals in the near-infrared range of 0.95~1.65 μm, and outputs TTL signals in real time.

Product features：Spectral response band: 0.95 ~ 1.65 μm、 Metal packaging, light and compact design、 Independent pixel operation、 Pixels can detect weak photon signals、 Dead time and Geiger avalanche signal detection threshold are adjustable

Application area：Distance measurement through fog, haze, smoke, etc、 Near-infrared laser alarm、 Long-range laser distance measurement、 Long-range space laser communication
