Abstract
PURPOSE: To make the infrared ray transmission window more difficult to break as compared to that of conventional ones by using the same material as that of ZnSe substrate as the base material for interference thin film and dispersing metal fine particles in the interference thin film.
CONSTITUTION: A metal such as Au of a higher reflectance to the wavelength of incident light and ZnSe are alternately heated and evaporated by electron beams onto a ZnSe substrate 1, whereby the metal fine particles are dispersed in the ZnSe and an interference thin film 5 of good abhesiveness to the substrate 1 and of a resembling coefficient of expansion is formed. Further a ZnSe thin film 3 is evaporated thereon. In this infrared ray transmission window, the theoretical thickness of the thin film 5 for reflection to become 0 with respect to the incident light 4 of a wavelength of 10.6μm becomes 0,71μm and refractive index 3.72. Here, the refractive index of the substrate 1 is assumed to be 2.4, that of the thin film 3 to be the same and the thickness of the thin film 3 to be 1.10μm.
