Title:
COMPOUND LENS MANUFACTURING DEVICE, METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/049450
Kind Code:
A1
Abstract:
The purpose of the present invention is to enable the optical axis of a base material lens and the optical axis of a mold to be aligned with each other easily in a compound lens manufacturing device, method, and program. A control unit performs: first processing for changing the distance between a mold and a photographing unit; second processing for acquiring two images including the mold before and after the change in the distance; third processing for detecting the center of the mold from each of the two images; and fourth processing for, when a first displacement in a direction orthogonal to the optical axis of a base material lens L at the central position of the mold in the two images is greater than a first threshold, receiving an operation for relatively moving the photographing unit and the mold in the direction orthogonal to the optical axis of the base material lens L to reduce the first displacement. The control unit repeatedly performs the first to fourth processing until the first displacement becomes the first threshold or less.
