Embedded use, fiber coupling type 1 ch SPAD module (for VIS to NIR region)

The C16534-050GD 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). As this product is compact and lightweight, it is suitable for integration into devices.
