Title:
PROCESS FOR PRODUCING OPTICAL ELEMENT
Document Type and Number:
WIPO Patent Application WO/2005/118502
Kind Code:
A1
Abstract:
A process for producing an optical element through bonding of multiple optical members by means of an adhesive, in which satisfactory exertion of optical performance can be accomplished and in which satisfactory adhesion strength avoiding any detachment at bonded position can be ensured, simplifying alignment to be conducted. There is provided a process for producing an optical element through bonding of two or more optical members by means of an adhesive, characterized in that with respect to at least one of adherend surfaces opposed to each other at at least one joint plane of the optical members, the concerned adherend surface is dry cleaned while masking at least any plane adjacent to the adherend surface, and that thereafter a liquid adhesive is applied onto the cleaned surface and hardened to thereby accomplish bonding.
