Aluminum Coated Mirrors
Aluminum Coated Mirrors
The average reflectance of aluminum-coated mirrors from 450nm to 10μm is more than 88%, and the reflectance is less affected by the change of wavelength and incident Angle. However, the aluminum film is easy to oxidize, so it is necessary to coat the aluminum film with another protective film.
