Method for detecting light-passing efficiency of optical lens by using optical lens parameter detecting instrument

The invention relates to a method for detecting the light-passing efficiency of an optical lens by using an optical lens parameter detecting instrument. The optical lens parameter detecting instrument comprises a support seat, a detected lens assembly, and a digital video camera, wherein the detected lens assembly and the digital video camera are installed on both ends of the support seat, respectively. The support seat is provided with an intelligent image processing device connected with the digital video camera to process and analyze image information. The image information output by the digital video camera to the intelligent image processing device is uncompressed digital video image information. The method not only fast detects the light-passing efficiency of the optical lens, but also has advantages of no strict working environment requirement and good convenience in operation.
