PRECURSOR COMPOSITION FOR OPTICAL RESIN, RESIN FOR OPTICAL USE, OPTICAL ELEMENT, AND OPTICAL ARTICLE

摘要

The optical element of the present invention has a first member and a second member which have been joined in close contact, and has nd1 > nd2 and (nF1 - nC1) < (nF2 - nC2), where the first member is formed of a resin having both a benzene ring and a fluorine atom, or the second member is formed of a resin having an alicyclic structure. It also makes use of an optic-purpose resin precursor composition prepared by mixing a first resin precursor having nd < 1.50 and (nF - nC) > 0.003 in an uncured state and a second resin precursor having nd < 1.62 and (nF - nC) > 0.010.
