| Abstract: | Photo-detector＇s absolute spectral responsivity embodies its ability on transition between photon and electron. It is a very important parameter to the photo-detector. Introduced how to adjust the visible intensity stabilized laser system, and then, the photo-detector＇s absolute spectral responsivity has been measured accurately on seven wavelengths in visible range. Its results and the measurement uncertainty have been analyzed finally. |
