OPTICAL COMPONENT USING COMPOSITE SUBSTRATE AND PROCESS FOR PRODUCING THE OPTICAL COMPONENT

摘要

A resin composition (2) such as a photocurable resin composition or a heat curable or thermoplastic resin composition is placed on an optical substrate (1). A printing pressure is applied to the assembly by an extra-flat pressing plate (3) that has a plane with a much higher flatness than the flatness of the optical substrate (1). The resin composition is cured by utilizing light or a temperature change to form a composite substrate. A thin film (4) such as a functional inorganic optical thin film, a dielectric multilayered optical thin film, or an optical functional metallic thin film is stacked on the composite substrate, for example, by low-temperature sputtering or ion beam sputtering to form an optical component such as a reflection mirror, a beam splitter, a band-pass filter, a band-stop filter, and an edge filter.
