Abstract

PURPOSE:To permit measurement of all kinds of lenses, by moving an auxiliary lens in the optical axis direction or replacing it with another. CONSTITUTION:The second collimator lens 36 is moved in the optical axis direction so that the focul point b1 formed by the light reflected from the curved surface of a lens being measured coincides with the curvature center of the lens curved surface. Interlocking with the movement of the lens 36, a corner cube 41 moves with a given relationshp thereto. Then, when the lens 36 is moved in the direction perpendicular to the optical axis, focul points a2 and b2 on a screen 39 move. Therefore, the lens 36 is moved in both the vertical and horizontal directions so that the focul point a2 coincides with the optical axis center. In the visual field of an ocular 40, if there is eccentricity in the curved surface being measured, the position of the image b3 of the light reflected from said curved surface deviates from the light image a2 formed by the optical axis aligning system comprising the corner cube 41 and a concave mirror 42. Accordingly, measuring the deviation P permits the eccentricity amount of said curved surface to be obtained.
