Abstract
A mirror having improved resistance to heat distortion and loss of dimensional stability when exposed to heat radiation . The mirror has a substrate of glass or plastic having front and back surfaces which can be of similar or different shape , and is coated with similar or dissimilar low-emissivity reflected layers on both surfaces. Radiation is reflected by the back surface (away from the mirror) thereby reducing amount of energy which is absorbed at the back surface of the mirror. This equalizes the temperature through the mirror and reduces thermally included warping of the mirror.
