SPAD module


Fiber coupling type 1 ch SPAD module (for VIS to NIR region)


The C16533-050GD is a fiber coupling type photon counting module that can detect low-level light. It consists of a thermoelectric single photon avalanche diode (SPAD), an amplifier, a comparator, a SPAD bias circuit, and a temperature controller. The module operates by simply connecting to an external power supply (±5 V).

- Fiber coupling type
- Single photon counting is possible.
- High sensitivity in the long wavelength range
- Low dark count
