Title:
LENS OPTICAL CHARACTERISTICS MEASUREMENT DEVICE, LENS OPTICAL CHARACTERISTICS MEASUREMENT METHOD, PROGRAM, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/059531
Kind Code:
A1
Abstract:
Provided is a lens optical characteristics measurement device that is capable of measuring in accordance with the power of the lens or is capable of measuring large-diameter lenses. This lens optical characteristics measurement device (1) comprises: a lens holding unit (18); a lens position moving unit (16); an operation input unit (11); a measurement control unit (12); a measurement calculation unit (13); a light irradiation unit (17); a light-receiving unit (19); and an output unit (15). The lens position moving unit (16) can move the lens held by the lens holding unit (18), in the X-axis, Y-axis, or Z-axis directions, on the basis of measurement control information. The X-axis and Y-axis directions are mutually orthogonal in the vertical direction or in a plane perpendicular to the optical axis direction. The Z-axis direction is the vertical direction or the optical axis direction for the optical system. The device can execute measurement in at least one measurement mode among three measurement modes, using control by the measurement control unit (12).
