摘要

PROBLEM TO BE SOLVED: To provide a centering method for cemented lens capable of improving productivity of the cemented lens by automating a part falling under a labor-intensive working method requiring skill.;SOLUTION: The automated centering method for cemented lens according to the present invention includes steps of: blowing compressed air to an upper-side lens L2 during rotation of a cemented lens L that comprises a lower-side lens L1 and the upper-side lens L2 with an uncured ultraviolet curable resin interposed in the bonded surface whose concave surface is the lower side and the convex surface is the upper side, and laterally displacing the upper-side lens in the radial direction; and determining whether or not a transmission deviation angle ε is present within a predetermined target tolerance range ε0, when the transmission deviation angle ε is outside the target tolerance range ε0, executing the previous step again and, when the transmission deviation angle ε is within the predetermined tolerance range ε0, irradiating the cemented lens L with ultraviolet ray.;COPYRIGHT: (C)2013,JPO&INPIT
