ABSTRACT:
Recently, there has been the tendency to increasingly use optical machinery and devices which utilize optical parts made of synthetic resin. Since an antireflection coating film for these synthetic resin optical parts is high in adhesive strength and is hard, it is advantageous to use silicon oxide. Particularly, silicon monoxide (SiO) varies in refractive index by varying the evaporation condition, and therefore, it is possible to make use of such properties to produce a multi-layered antireflection coating film from a single evaporation material by varying the evaporation conditions.
