  • Patent number: 4448855
    Abstract: The present invention is intended for a heat resistant reflector in which a light reflective metal is vacuum coated on a metal or inorganic material substrate and in which on the surface of the vacuum coated layer is further vacuum coated a light transmissible ceramic and preferably, a ceramic having a crystalline substance. This reflector has a light reflective metal and a ceramic vacuum coated together, and thus, can form a thin film of the same replica as a substrate. Therefore, there is very little refraction or absorption of light due to a protective film, cnanges of total reflectivity, regular reflectivity or refractivity are very few and its manufacture as well is simple because of continuous vacuum coating with one and the same coating machine.
