    Abstract: PROBLEM TO BE SOLVED: To provide a dichroic mirror produced by using a planar substrate such as glass and bending or tempering a mirror by heart treatment. SOLUTION: The heat-treatable dichroic mirror has a transparent substrate having 650-800 deg.C glass transition temperature and a plurality of films by sputtering supported on the substrate. The plurality of films are at least two pairs of continuous films, the refractive indexes of each of the pairs of films are different by about >=0.2 and a reflective interface is provided between these films. The heat-treatable dichroic mirror after heat treatment has >=24% transmittance, >=45% reflectance and about

    Abstract: A heat-treatable dichroic mirror, comprising a transparent substrate having a glass transition temperature in the range of 650-800° C., and a plurality of sputtered films carried on said substrate and forming at least two pairs of contiguous films in which the films of each pair have disparate refractive indices differing by at least about 0.2 so as to provide between them a reflective interface. The films include an oxide of a metal such as titanium, a second film comprising an oxidizable metal or semi-metal such as silicon, and a protective overcoat of a thickness and composition sufficient to substantially prevent permeation of oxygen therethrough when heat treated at said glass transition temperature. The mirror, after said heat treatment, exhibits a transmittance of at least 24% in the wavelength range of 550-650 nm, a reflectance of at least 45%, and a haze of not greater than about 1%.

    Abstract: A heat formable mirror is formed by sputter depositing upon a sheet such as glass a reflective coating utilizing a base layer of silicon or a combination of silicon and stainless steel films, a reflective layer formed of a reflective metallic film such as niobium, titanium or aluminum, and a protective layer comprising preferably silicon nitride. The resulting mirror can be heat formed at elevated temperatures to form a curved mirror having a reflective coating free of objectionable defects.
