Flexible Curved Optics Elements With Laminate

Case ID:

The invention is a means of allowing a substrate like glass, a mirror or plastic, to flex after a coating is applied.


Flexible glass is employed as a substrate for vapor deposited thin films to create low-cost curved mirrors in shapes like parabolic, hyperbolic, etc. The elasticity of substrate material may be exploited to create free-standing contours defined by an underlying mechanical constraint. These flexible mirrors may be tiled as a means of laminating larger curved surfaces. This invention eliminates the need for deposition of complex multilayer coatings by allowing for standard deposition onto a flat flexible glass substrate and forms flexible glass onto an underlying supporting substrate.
