Filed: 2002-06-11
Abstract: <P>PROBLEM TO BE SOLVED: To provide an optical part manufacturing method in which an optical part is made small-sized and manufactured with high-quality even if the adhesion and strength of the film coated on the optical part made by sticking a plurality of elements can be maintained at a high degree, and to provide stuck elements manufactured by the method.  <P>SOLUTION: Since the optical part is manufactured by sticking at least two members 1, 2 to each other and thereafter treating them by coating, the so-called "holding parts" are not prepared for each of them, therefore, the optical part can be downsized, compared with the case that the members 1, 2 are individually treated by coating. Moreover, if the coated surfaces are scratched after having stuck the parts 1, 2, they do not need to be separated again to correct the scratch, so that labor and time for manufacture is saved. Further, since the coating treatment of the whole optical parts can be carried out at a time, such a problem can be avoided, as wrong color coating is not noticed until the parts 1, 2 have been individually treated by coating and assembled.  <P>COPYRIGHT: (C)2004,JPO
