Flexible Curved Optics Elements With Laminate

Case ID:
UA18-079
Invention:

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

 

Background:
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.

 

Applications:

  • Concentrated solar power systems
  • Concentrated photovoltaic systems
  • Reflective telescopes
  • Laser construction

 

Advantages:

  • Higher optical transparency
  • Improved thermal stability
  • Improved wear/abrasion resistance
  • Greater mechanical strength
  • Reduced optical degradation
  • Scalable for large volume applications via tiling
  • Improved thermal/mechanical shock resistance
  • Reduced mass and CTE
  • Reduced forming cost view
  • Pseudo self-forming
  • Significant simplification of thin film coating process
