The SPCM-AQRH-14-FC is a high-performance single photon counting module from Excelitas Technologies. It features a unique silicon avalanche photodiode (SLiK) with a 180 µm diameter active area and unmatched detection uniformity. This specific model, designated by the '14' code, is optimized with a 10 ns output pulse width, a 24 ns dead time, and a maximum dark count rate of 100 counts per second. It includes a factory-installed FC fiber adapter for easy coupling to multimode optical fibers. The module operates from a single +5V supply and includes built-in protection against accidental light overload. It provides a TTL-level output pulse for every photon detected and supports gated operation.
