4 Channel Single Photon Counting Array: SPCM-AQ4C Datasheet

Excelitas Technologies' 4 Channel Single Photon Counting Array, SPCM-AQ4C, is four channel photon counting card cable of detecting light over the wavelength range from 400nm to 1060nm. The SPCM-AQ4C module contains four APDs with a single power supply and four individual outputs and features peak photon detection efficiency at 650nm: 60% typical and a 0.5% probability of afterpulsing.

Excelitas Technologies supports custom requirements for these modules including dark count, afterpulse, and peak photon detection efficiency. The SPCM-AQ4C 4 Channel Single Photon Counting Array is ideal for particle Sizing, confocal microscopy, adaptive optics and astronomical observations, LIDAR, and ultra-sensitive fluorescence.
