SIMTRUM'S Photon counting module is an ultra-sensitive photodetector based on Si-APD technology. It operates over a wavelength range of 400 to 900 nm and can function in both linear mode and Geiger mode. The features a unique high-performance active suppression circuit that enables continuous single-photon detection. This circuit achieves avalanche suppression greater than 20 dB, optimizing the performance of the Photon counting module.In the 850 nm wavelength range, the detection efficiency exceeds 80%, with a dark count rate of 100 counts per second and a dead time of less than 150 ns.

LA-SR01-Si-APD-F operates in a low-temperature environment of -20 °C through internal refrigeration to achieve the best signal-to-noise ratio. The refrigeration module is controlled by an efficient TEC, with a control accuracy of ±0.2 °C.

Attention

  • Incorrect voltage may damage the module. Ensure that the power supply is correctly connected.
  • APD is a highly sensitive photodetector. The input light signal strength should be controlled in avalanche mode, as excessive light intensity may damage the APD, which can reduce its detection sensitivity and, in severe cases, even lead to diode breakdown.
  • In special applications, the module's operating temperature should not exceed 50 °C, as elevated temperatures may cause an increase in the APD's operating temperature, leading to higher dark count levels.
