TRANSPARENT MOLDED ARTICLE AND METHOD FOR PRODUCING IT, AND LENS SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To provide a transparent molded article in which fine particles are uniformly dispersed in a resin matrix and which has excellent transparency and high refractivity, a method for producing it, and a lens substrate. SOLUTION: The transparent molded article having a thickness of≥0.5 mm contains fine particles containing zirconium oxide as a main component in the resin and has a light transmittance of≥60% at a wavelength of 405 nm and≥70% at a wavelength of 589 nm in terms of the article having a thickness of 1 mm.
