Abstract
PURPOSE: To improve the efficiency of the lens inspection by comparing the optical characteristic of a lens to be inspected with that of a reference lens by means of a digitized signal and by checking the numeric signal to inspect the lens.
CONSTITUTION: Diffused light ray from the slit 5 is made a parallel ray in the axial direction by the collimator lens 6 and is applied to the lens 7 to be inspected. The light ray from the lens 7 is made a parallel ray in the axial direction again by the auxiliary lens 8, and a slit image is formed on the face of the image pickup tube of the ITV camera 13 through the image forming lens 9 and objective 11. Next the distribution of the intensity of illumination of the image signal of the ITV camera 13 is taken as a time series signal by a time of scanning the scanning line of the scanning signal of the ITV camera, respective physical quantities are measured as digital signals to evaluate the lens to be inspected. That is, the peak intensity I, distribution width, quantity Δ of a peak position shift and focus difference x can be measured from the said time series signal by using the signals 16, 17 corresponding to the slit image.
