Metal Mirrors » Enhanced Aluminum

Enhanced Aluminum is comprised of aluminum overcoated with a multilayer dielectric film that is designed to optimize reflectance at a specific wavelength. The enhancing layer also greatly improves durability, meeting MIL SPEC requirements.

This coating is more sensitive to wavelength, angle of incidence and polarization than protective metal coatings.

Enhanced Aluminum is used to enhance the reflectivity of Bare Aluminum, most commonly in the ultraviolet region. At 193nm, Bare Aluminum will deliver about 91% reflectivity. Using Enhanced Aluminum at the same wavelength will deliver greater than 98% reflectivity.

Reflectance values can be optimized further by adding more layers to the enhancing overcoat. This option is available upon request.
