Single-photon detector, photosensitive area 300 μm SPD300A-APC

LBTEK single-photon detectors achieve a detection efficiency exceeding 55% at 700 nm wavelength, with dark counts <500 cps and dead time less than 50 ns, designed for fiber optic input. In specific application scenarios, ensure the module's operating temperature does not exceed 50 °C, as excessively high temperatures may cause the APD's operating temperature to rise, leading to increased dark count levels. APDs are highly sensitive photodetection devices; during avalanche mode, the input optical signal intensity should be controlled. Excessive light intensity may damage the APD, potentially reducing its detection sensitivity or, in severe cases, causing diode breakdown.
