The C11202-050 is a single-channel SPAD module designed for photon counting in the visible spectrum, featuring a ϕ50 μm photosensitive area. It operates with a ±5 V power supply and includes thermoelectric cooling to maintain a fixed chip temperature of -20 °C. The module offers a peak sensitivity wavelength of 450 nm, a photon detection efficiency of 60% to 70%, a dark count rate of 7 to 25 cps, and a maximum count rate of 30 Mcps. Its digital output is TTL compatible, and it is rated for operation from -10 °C to +40 °C. The module is housed in a compact package with SMB output connector and requires an external power supply capable of delivering 1.5 A or higher.
1 ch SPAD module (for VIS region)
The C11202 series is a photon counting module capable of detecting low light levels. The C11202 series is made up of a thermoelectric cooled single photon avalanche diode (SPAD), 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 photosensitive areas offer a low dark count. Modules operate just by connecting them to an external power supply (±5 V).
Features
- High sensitivity in the short wavelength range
