Avalanche Photodetector APD-AS400A

    LBTEK's avalanche photodetector series covers silicon and indium gallium arsenide types, offering both adjustable gain and fixed gain options. They are suitable for low-light power level applications and can precisely meet various low-light detection needs. The adjustable gain series allows users to adjust the reverse bias voltage across the diode via a rotary knob on the side of the housing, thereby changing the gain level. Using a BNC-SMA signal cable, connect the photodetector's signal interface to downstream acquisition devices such as oscilloscopes. The detector's mechanical housing features SM05 internal threads and SM1 external threads on the surface, along with M4 threaded holes at the bottom for easy mounting onto posts. Each photodetector comes with a power supply.

    Note: This product series includes a sleeve with SM1 internal threads, which can be removed as needed during use (both the STEP and PDF files include this sleeve).

   The appearance of the fixed gain models has been updated, and both old and new appearances may be shipped randomly.
