を特徴とする偏心測定装置。 Project the target image onto the spherical center of the surface to be measured of the lens to be measured through the imaging lens, measure the amount of deviation of the reflected image of the target from the surface to be measured from the reference surface, and calculate the inclination of the surface to be measured from the measured value. An eccentricity measurement device that uses a mirror that bends the measurement axis at right angles, a corner cube that is movable in the direction of the optical path on the optical path reflected by this mirror, and a mirror that covers the optical path that is folded back by the corner cube. It has another mirror that is bent toward the measurement lens, and a parallelism observation optical system that is disposed at a position opposite to the corner cube and for observing the inclination due to the movement of the corner cube, An eccentricity measuring device characterized in that it is possible to correct the inclination of a corner cube while observing the parallelism of the recorner cube using the parallelism observation optical system.
