Introduction: | Gold is the most efficient metalic reflective coating over the entire IR range. And a protective layer of SiO can be used to protect the gold coatings and to make the mirror easy to clean.Bare gold coated mirror has higher reflection, but easier to get scratched.
Bare or protected gold-coated concave mirrors are designed for light collection, imaging, and focusing applications. These reflective optics focus light without chromatic aberration, making them especially suitable for broadband sources. |
