METHOD, DEVICE AND PROGRAM FOR MEASURING ASPHERIC LENS, MANUFACTURING METHOD OF ASPHERIC LENS, AND ASPHERIC LENS

摘要

PROBLEM TO BE SOLVED: To provide a measuring device and measuring program that can separately measure a face-to-face tilt amount and a face-to-face shift amount of an aspheric lens accurately in a short time and has a simple constitution allowing such a measurement. SOLUTION: The measuring device measures eccentricities of a first face R1 and a second face R2 of the aspheric lens 1 are measured, and the face-to-face shift amount and a face-to-face tilt amount are calculated based on the measurement result. The eccentricities of the first face R1 and second face R2 are measured by: a first process of measuring the eccentricity of the first face R1 with reference to a second reference axis of which angle to the aspheric axis of the second face R2 is known; a second process of measuring the eccentricity of the second face R2 with reference to the second reference axis; and a third process of measuring the eccentricity of the second face R2 with reference to a first reference axis of which angle to the aspheric axis of the first face R1 and the position of the intersection point to the second reference axis are known.
