Abstract
To substantially improve measurement accuracy by a simple constitution, in a technique for measuring the amount of eccentricity to which an autocollimation method is applied. A lens to be inspected is set at a prescribed position of rotation angle (S3), horizontal lines P1 and P2 which intersect with an image vertical line of a reticle are set (S4), vertical lines Q1 and Q2 which intersect with an image horizonal line of the reticle are set (S5), an A-point and a B-point of light intensity peak locations on the horizontal lines P1 and P2 and a C-point and a D-point of light intensity peak locations on the vertical lines Q1 and Q2 are specified (S6, 7), and a cross-shaped vertical line, connecting the A-point and B-point and a cross-shaped horizontal line connecting the C-point and the D-point are determined (S8, 9). After this, the intersection between the cross-shaped vertical line and the cross-shaped horizontal line is specified (S10) to specify the center position of gravity of light intensity within a square region centered at the intersection to be the center point R of the image of the cross-shaped reticle (S11). A locus circle of image center is determined, on the basis of each center point R at a plurality of rotational positions (S14), and the radius of the locus circle of image center is taken as the amount of eccentricity Ec of the surface to be inspected (S15).
