Title:
LENS OPTICAL-CHARACTERISTICS-MEASURING DEVICE, LENS OPTICAL-CHARACTERISTICS-MEASURING METHOD, PROGRAM, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/059515
Kind Code:
A1
Abstract:
Provided is a lens optical-characteristics-measuring device with which it is possible to easily read an in-lens mark. This lens optical-characteristics-measuring device comprises a lens-holding unit (18), a lens position movement unit, an operation input unit, a measurement control unit, a measurement computation unit, a light-radiating unit (17), a light-receiving unit (19), and an output unit. The measurement control unit causes a lens (Le) held by the lens-holding unit (18) to move to above or below an optical-characteristics measurement reference position by means of the lens position movement unit, and irradiates the lens (Le) that is above or below the aforementioned position with light from the light-radiating unit (17). The light-receiving unit (19) receives emission light emitted from an in-lens mark located within the lens (Le) that is above or below the optical-characteristics measurement reference position. The measurement computation unit generates in-lens mark-reading information from the emission light from the in-lens mark as received by the light-receiving unit (19). The output unit outputs the in-lens mark-reading information.
