Bare Gold (BAU)
Bare Gold has high reflectance in the near, mid and far IR regions.
Gold does not oxidize, so it is not necessary that it have a protective
dielectric overcoat. However, bare gold is very soft and easily
scratched, and can only be cleaned by flow-washing with solvents, or by
blowing the surface clean with a low pressure stream of dry air.
Durability is greatly enhanced with a protective overcoat. Protected
gold can be cleaned regularly using standard organic solvents. Gold is
chemically inert, thus it is well suited for harsh environments, such
as DF and HF laser cavities.
