Abstract

PURPOSE: To improve inspecting accuracy by forming the transmitted image and the reflected image by an inspecting lens of light from specified light sources on a screen by a lens having the same optical axis as the inspecting lens.
CONSTITUTION: The light L1 to obtain the transmitted image is supplied to the inspecting lens 11 from the 1st light source 13 and the light L2 from and 2nd light source 14 is supplied to the reflection surface 11r of the lens 11 through a separation mirror 15, then the transmitted image and the reflected image from the lens 11 are formed into an image on the screen 16 by the lens 12 having the same optical axis as the lens 11. Thus, the inclination of the lens 11 is measured by deviation between the transmitted image and the reflected image on the screen 16.
