OPTICAL MEMBER, IMAGE PICKUP APPARATUS, AND METHOD FOR MANUFACTURING OPTICAL MEMBER

摘要

This invention provides an optical member in which ripple is suppressed and a porous glass layer is formed on a base member and also provides a method for easily manufacturing the optical member.;An optical member has a base member (1) and a porous glass layer (2) formed on the base member (1), in which a textured structure is formed on the interface contacting the porous glass layer (2) of the base member (1) and the height of the textured structure is 100 nm or more and equal to or lower than the thickness of the porous glass layer (2).
