To improve the transmission efficiency and the photoelectric conversion signal without distortion of optoelectronic products, photodetectors and the signal not only to the optical system to match the laser photoelectric products, but also to the subsequent electronics and match features and operating parameters with respect, so that each an interconnected 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 a measurement wavelength of ultraviolet, the selection of a photomultiplier tube or specialized Ultraviolet semiconductor devices; if the signal is visible, you can choose a photomultiplier, photoresistor and Si optoelectronic devices; if it is an infrared signal semiconductor optoelectronic products, the selection of the photosensitive resistance, near-infrared selection Si photovoltaic device or photomultiplier tube; photoelectric detector must modulated light signal, the signal frequency and waveform match, which guarantees no frequency distortion of the output waveform and a good time response. This is mainly select short response time or a high maximum frequency of the device, but also pay attention to a good match on the circuit dynamic parameters; lighting optoelectronic products Huadu District _ _ gold-precision optical products provided by Huizhou Hing Precision Parts Co., Ltd. .
