PROTECTED AND ENHANCED METAL MIRROR COATINGS

COATING DESCRIPTION:

A protective dielectric coating is usually applied on top of the bare metal in order to improve the scratch resistance and environmental durability of the bare metal coating. In addition, a multi-layer dielectric stack can be applied in order to increase the reflection over a narrow wavelength region as the design shows in this graph.

OPTICAL PERFORMANCE:

This is dependent on the particular metal and the wavelength region.

DURABILITY PERFORMANCE:

Adhesion, moderate abrasion, and humidity as per the following (where applicable): MIL-C-675, MIL-M-13508, MIL-M-14806, MIL-C-48497, MIL-F-48616, MIL-STD-810F
