とを特徴とするレンズの表面形状測定器。[Claims for Utility Model Registration] In a measuring instrument for measuring the surface shape of a lens by scanning a stylus along the surface to be measured of the lens, the scanning line of the stylus and the scanning line of the stylus are directed toward the lens. A light irradiation unit for irradiating light rays traveling in orthogonal directions is provided, and the light rays that have passed through the lens are received on the course direction line of the light rays heading toward the lens, and the light rays are emitted by the deviation between the optical axis of the lens and the light rays. Measurement of the surface shape of a lens, characterized in that an optical sensor is provided to detect a deviation in the incident position of a light beam that occurs when the beam is refracted, and the position of the lens can be adjusted in a direction to eliminate the deviation in the incident position. vessel.
