EMF offers a broad range of aluminum coatings for first and second surface mirrors functioning across a wide wavelength range. Aluminum coated mirrors are an excellent option for many general broadband applications. Because bare aluminum is very susceptible to damage, a protective SiO2 overcoat is layered over the aluminum to enhance the durability of the coating. A protected or enhanced aluminum coating has less chance of tarnishing than protected silver in a high humidity environment and has good reflectance so in many cases, these coatings are preferred over a protected silver coating.
