Patent ID: 8439511

Claim:
A mirror comprising: a laminated substrate having a first surface and an opposed second surface; said substrate of a material having thermo-mechanical stability, low mass and stiffness for providing a shape to the mirror; a front non-specularizing buffer layer immediately adjacent to and contiguous with said substrate on said first surface; said front buffer layer is made of ester resin to buffer the surface morphology of said first surface of said substrate; a front specularizing layer immediately adjacent to and contiguous with said front buffer layer; said specularizing layer is pre-fabricated and made of a material for providing a smooth, low scatter optical surface; a rear buffer layer immediately adjacent to and contiguous with said substrate on said second surface; a rear film layer immediately adjacent to and contiguous with said rear buffer layer; and wherein said rear buffer layer and rear film layer are of a material providing thermo-mechanical balance to said front buffer layer and front specularizing layer and having coefficient of thermal expansion (CTE) to balance the difference in CTE between the substrate and the front buffer layer and the front specularizing layer.
