Avalanche photodiode calibration system O'zbekiston

This product is an avalanche photodiode calibration system with independent intellectual property rights. It is used for the test of avalanche photodiodes and supports two working modes of Geiger free running. Support the customized development of fixtures, which can realize the non-destructive testing of any packaged devices. Widely used in device performance testing, academic research and other fields.
This product supports the test of avalanche photodiodes in gated mode and free-running mode, analyzes the detection pulse through the time data conversion (TDC) function, and completes the test of key indicators such as detection efficiency, dark count, and post-pulse. In gated mode, the trigger frequency is up to 1.25GHz, the bias voltage control range is 10V~80V, and the temperature control adjustment range is 5~-60℃. Support the adjustment of key parameters such as bias voltage, dead time, discrimination threshold, gating amplitude, and coincidence delay. Combined with a high-speed picosecond pulse light source, the single-photon characteristics of the device can be analyzed.
