Document Type and Number:
WIPO Patent Application WO/2020/230341
Kind Code:
A1
Abstract:
Provided is a lens optical characteristic measurement device capable of measuring the optical characteristics of a lens for various lens positions and directions. This lens optical characteristic measurement device (1) comprises a lens holding unit (18), an operation input unit (11), a measurement control unit (12), a measurement calculation unit (13), a light emission unit (17), a light reception unit (19), a lens position movement unit (16), and an output unit (15). The lens position movement unit (16) is coupled to the lens holding unit (18). The lens position movement unit (16) is capable of moving the lens held by the lens holding unit (18) in at least three directions from among the six directions consisting of the X-axis direction, Y-axis direction, Z-axis direction, Xθ direction, Yθ direction, and Zθ direction on the basis of measurement control information. Optical characteristics can be measured for various lens positions and directions.
