The principle of TTI photoelectric converter is that the conductivity of the irradiated material changes due to radiation. Photodetectors have a wide range of applications in various fields of military and national economy. In the visible or near-infrared wavelength range, it is mainly used for radiation measurement and detection, industrial automatic control, photometric measurement, etc; In the infrared band, it is mainly used for guidance, infrared thermal imaging, infrared remote sensing, and other fields.

The BNC interface of TIA-525, TIA-527, TIA-952 series photodetectors can be directly connected to oscilloscopes or digital receiving devices. TIA-1200, TIA-2000, TIA-3000, TIA-4000 are K-type SMA female ports. Fiber optic coupling and free space input are optional, and can be adapted to various fiber optic inputs using patch cords or adapters. TIA-525 and TIA-527 can be powered by batteries and power adapters.
