摘要

A lens optical characteristic measuring apparatus capable of evaluating various distances and directions through a spectacle lens without assuming an object to be observed such as a target plate is provided.The lens optical characteristic measuring apparatus of the present invention isLens holding partOperation inputMeasurement control departmentMeasurement operation DepartmentLight irradiation part (17).Light receiving part (19).Lens position moving sectionAndProvide an outputLens position moving sectionConnect to lens holderLens position moving sectionBased on measurement control informationLens (RE) held in lens holding partX θ DirectionAndY θ It is movable in the direction.The virtual eye rotation point (G1) is assumed on the light irradiation part (17) side of the lens (LE).The optical axis is regarded as a virtual line of sight passing through the virtual eye rotation pointThe optical characteristics of the exit pupil plane of the lens (LE) are measured for each of the virtual gaze directions of various angles.
