Si Amplifier Photodetector 400nm-1100nm (5MHz)   2022-06-27    


PDAM005B-Si photodetector is a rated bandwidth, fixed gain photodetector used for detecting optical signals. The optical signal is input from the photoelectric sensor surface, and the output is in the form of voltage through BNC.  This product can measure the optical signal in the wavelength range of 400nm to 1100nm. Refer to appendix table for specific performance parameter data. The housing of the LD-PD photodetector has inch 1/4"-20 threaded mounting holes, which can be easily installed and fixed. The housing part also comes with two different sizes of threaded adapters, which are suitable for industrial and scientific research applications, it can be easily adapted to external optical components, such as filters, attenuators, lenses, FC fiber adapters, etc. This product includes a plastic dust cover. Please refer to the third chapter for specific installation. Each photodetector is equipped with a linear DC power supply with an output of 9V, and the rated input voltage of this DC power supply is 220VAC/50Hz.
