Ultraviolet Sensor Module

---

This sensor is engineered for the efficient operation of an avalanche photodiode (APD) in conjunction with an active quenching circuit. It facilitates verification of the APD's functionality in Geiger mode, assesses light detection efficacy, and accommodates the application of a variable high voltage ranging from 0 to 200V to the optical sensor.

To maintain accuracy despite temperature fluctuations, the sensor is equipped with a temperature compensation circuit that adjusts for variations in the breakdown voltage due to temperature changes. Calibration of the high voltage, temperature compensation, and precision tuning can be easily managed via a graphical user interface (GUI).

The sensor module, requiring an input power of 5V, allows for signal output observation through an oscilloscope. The TO-5 packaged optical sensors are readily operational, and compatibility with other optical sensors is achieved via a separate dummy mount.

This assembly combines a silicon carbide (SiC) avalanche photodiode with a UV sensor module that operates through an active quenching circuit. This setup is adept at measuring fluorescence and detecting ultraviolet rays at the single-photon level.
