The DET30 bias photodetector is a compact, unamplified, fiber-optic input, battery-powered detector with very low noise, and can be used to detect optical signals with ps-level pulse widths.
The photodiode material is silicon, and the response spectrum is 300-1100nm; UV enhancement at 355nm; with a large target surface of 3000um, it is very suitable for doing low light detection, fluorescence detection and other applications.
The spatial resolution is related to your optical pulse parameter setting, which is set according to the monitoring length of the fiber optic cable. 40km distance we can achieve 5m spatial resolution.
