Title:
レンズホルダ取付精度確認システム、レンズ取付台及びレンズ加工システム
Document Type and Number:
Japanese Patent JP4812522
Kind Code:
B2
Abstract:
A system for verifying accuracy of lens holder attachment comprises the step for applying a mark in advance in a reference position in which attachment of a lens holder (12) is anticipated on a convex lens surface (1A) of a reference lens (1); the step for attaching the lens holder to the convex lens surface of the reference lens by using a holder attachment apparatus; and the step for comparing a position in which the lens holder is actually attached and a reference position in which the mark is applied on the lens. A cavityshaped hole (28) is formed in the holder (12) so that a position of the mark on the reference lens can be observed when the lens holder is attached to the lens. In the comparison step, a toolmaker's microscope (31) is used to observe the mark through the hole in the lens holder (28) from a direction of the convex lens surface of the lens, an actual attachment position of the holder is compared to the reference position of the reference lens, and an attachment accuracy of the holder is verified.
