Enhanced Aluminum (EAL)
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 sensitive to wavelength, angle
of incidence and polarization. Reflectance values can be optimized further
by adding more layers to the enhancing overcoat. This option is available
upon request.
