Aluminum Metallic Mirror Coating

Aluminum Metallic Mirror Coating

Enhanced Aluminum Metallic Mirror Coating

EMF offers a broad range of aluminum metallic mirror coatings for first surface mirrors and second surface mirrors 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 applied over the aluminum coating 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 while providing good reflectance. So, in many cases, an aluminum metallic mirror coating is preferred over a protected silver coating.


Substrate Materials: Suitable for glass, plastic, metal, and ceramics,  substrates up to 90″ (2.3 meters)

Durability:  Meets specifications of MIL-M-13508 and various other military specifications.
