Single pixel photon counting module for low-light-level detection

The C11202 series is a single-photon counting module capable of detecting low light levels. The C11202 series is made up of a single-pixel thermoelectrically cooled MPPC, a signal amplifier circuit, a comparator circuit, a high-voltage power supply circuit, and a temperature control circuit. The photosensitive area is available in two sizes of ϕ50 μm and ϕ100 μm, and such small photosensitive areas offer a low dark count. Modules operate just by connecting them to an external power supply (±5 V).
