The C11202 series is made up ofa 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).Low-light-level measurementHigh sensitivity in the short wavelength rangeLow afterpulse Fluorescence measurementParticle diameter measurementLow dark countAnalytical instrumentFeatures Applications |
