Metal & Dielectric Mirror Coatings

Metal coatings can be applied as: Bare, Protected or Enhanced with dielectric layers. AccuCoat Inc. also produces Dielectric High Reflector coatings. These coatings can be applied to Glass, Molded & Diamond Turned Plastic, and Metal substrates. Many of these coatings have been tested to meet Military Specifications and High Laser Damage Threshold tests (LDT) and are finding their way into many new Solar applications. AccuCoat recently added the capability to coat polygons and spinners.

Coating Types:

• Aluminum (Al) • Gold (Au) • Chrome (Cr) • Dark Chrome • Tin (Sn) • Nickel (Ni)  • All Dielectric • Copper (Cu) • Inconel • Silver (Ag) • Titanium (Ti)

These coatings can be optimized for use as first or second surface mirrors or adjusted for specified wavelength or angle of incidence ranges.
