摘要： There is provided a glass member for optical parts that represents a greater absolute value |Δn| of refractive index difference Δn of visual light between base glass and heterogeneous phase region. In the glass member for optical parts, the heterogeneous phase region distinguishable by a different refractive index is formed at an intended location inside a glass by focused irradiation of a pulsed laser. When a multicomponent optical glass of SiO2, Rn2+RO, and TiO2 is used, |Δn| of no less than 0.005 can be attained under a lower irradiation intensity. It is suitable for optical parts such as optical low-pass filters, diffractive optical parts, optical diffusion parts, optical filters, lenses and microlens arrays.
