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