OPTICAL COMPONENT AND METHOD FOR MANUFACTURING OPTICAL COMPONENT

PROBLEM TO BE SOLVED: To control layer thickness of an adhesive layer with high accuracy and to increase optical characteristics. SOLUTION: A spacer 16 for gap adjustment is formed on the joining face 12S of prism blocks 12A, 12B, and an adhesive is supplied to fill the gap between the prism blocks...

description PROBLEM TO BE SOLVED: To control layer thickness of an adhesive layer with high accuracy and to increase optical characteristics. SOLUTION: A spacer 16 for gap adjustment is formed on the joining face 12S of prism blocks 12A, 12B, and an adhesive is supplied to fill the gap between the prism blocks 12A, 12B and cured to regulate the layer thickness of the adhesive layer 13 with high accuracy. The layer thickness of the adhesive layer 13 can be arbitrarily controlled by the formation height (formation thickness) of the spacer 16. Thus, a shift in the parallelism of the joining face 12S caused by uneven layer thickness or curing shrinkage of the adhesive layer 13 can be suppressed and required optical characteristics such as accuracy of wavefront aberration can be stably obtained.
