Abstract
Aerogel-based optical elements are disclosed. The aerogel-based optical elements have an aerogel member having at least one surface, and at least one optical surface disposed on the at least one aerogel member surface. The at least one optical surface comprises an electroformed metal or at least one glass sheet. The at least one optical surface can be transmissive, reflective, or both. Different types of aerogel-based optical elements are presented, along with various methods of making the aerogel-based optical elements.
Claims20
An aerogel-based optical element, comprising:
- an aerogel member having first and second surfaces;
- first and second layers of fixing material respectively disposed on the first and second surfaces;
- and
- first and second sheets applied to the respective first and second layers of fixing material, wherein at least the first sheet is a glass sheet.
