<P>PROBLEM TO BE SOLVED: To provide a method for preventing the phenomenon of a diamond-like carbon film in which moisture on a surface becomes water drops on the basis that it is water repellent and to provide the optical window of optical equipment utilizing the physical properties of high hardness, chemical stability and excellent transparency, etc., that the diamond-like carbon film is originally provided with. <P>SOLUTION: For this optical window of the optical equipment, a desired thin film such as the diamond-like carbon film is formed on a substrate and the surface is hydrophilic. Also, the arrangement is adopted to the optical window of equipment handling infrared rays. Also, this method for manufacturing the optical window is composed of a process of forming the thin film such as the diamond-like carbon film on the substrate and a treatment process of making the surface hydrophilic. <P>COPYRIGHT: (C)2004,JPO |
