Photoconductive device: the use of a semiconductor material having a photoconductive effect made photodetector called photoconductive devices, often called photoresistor. Several windows in the visible and atmosphere through, that the near-infrared, mid-infrared and far-infrared band, have applied to the light-sensitive resistors. Photoresistor is widely used in photoelectric automatic detection system, optical tracking systems, missile guidance, IR systems. To improve the transmission efficiency and the photoelectric conversion signal without distortion, the photodetector and the signal not only to the optical system to match the semiconductor optoelectronic products, but also to the subsequent electronics and match features and operating parameters with respect, so that each mutual connected devices are in the best working condition. Now apply the selection point detector has summarized as follows: photodetectors and radiation sources must match and spectral characteristics of the optical system with respect. If the measurement wavelength ultraviolet optoelectronic products, the selection of a photomultiplier tube or specialized Ultraviolet semiconductor devices; if the signal is visible optoelectronic products of choice, you can choose a photomultiplier, photoresistor and Si optoelectronic devices; if it is an infrared signal, Selection photosensitive resistance, near-infrared selection Si photovoltaic device or photomultiplier tube; semiconductor optoelectronic products, optical products, Guangzhou, Huizhou Jin Jin precision provided by precision parts Limited.
