測定装置。 In a lens eccentricity measurement device that measures the eccentricity of the lens surface by projecting an index image onto the spherical center position of a desired lens surface of the lens to be measured and guiding the reflected image from the front lens surface onto a two-dimensional sensor, the index and Two optical systems capable of focusing the index on two surfaces of the lens to be measured are arranged between the lens to be measured, and the two optical systems are arranged between the front beam splitter and the rear beam splitter. One optical system consists of a first collimator lens and a first objective lens provided between two reflecting mirrors, and the other optical system consists of a second collimator lens and a second objective lens. is placed on a goniometer stage, and the reflected images from the two surfaces of the lens to be measured are formed on a two-dimensional sensor.The goniometer is controlled by a microcomputer from the position of this image formation, and the mounting position of the lens to be measured is determined. A lens eccentricity measuring device characterized by adjustment.
