Protected gold reflectance
Did you know?
Webb(i) Gold does not corrode or rust while silver and copper do, which would reduce reflectance (by the way this happens before takeoff) and (ii) it’s a lot easier to work with gold than aluminum. The outer sun visor is made from polycarbonate plastic and coated with a thin layer of gold. This combination gives complete protection to the astronaut. http://rmico.com/protected-gold
WebbBare (Unprotected) Gold Mirrors. Bare gold mirrors provide good reflectivity from the NIR through the IR spectrum, with R avg > 98.5% from 1 – 10µc. Bare Gold. Unlike protected gold mirrors which have a thin dielectric layer that adds protection from abrasion, bare gold is soft and cannot be easily cleaned without damage. Webb14 nov. 2024 · Gold Mirror Coatings. Gold mirror coatings are used for applications in the 600 nm and longer wavelengths. Here, reflectivities well over 95% (sometimes around 99%) are achieved. It is possible, for example, to obtain an average reflectivity of 97% between 700 nm and 2000 nm with a protected gold mirror. Sometimes, an unprotected gold …
