High Reflectivity Dielectric Coatings (DHR)
Dielectric and Metallic Mirror Coatings
Dielectric Coatings (DHR type)
Multilayer Dielectric coatings can reach up to 99.8% reflection and are generally used for single wavelengths between 250nm and 2200nm. An example of a 1064nm coating is shown below.

Metallic High Reflective Coatings (MHR type)
We provide metallic high reflective coatings using Au, Ag, and Al. These coatings are applied to where a consistent high reflection in a wide spectral range is necessary. Their reflectivity are lower than dielectric DHR coatings, but can cover a wider spectral range. In order to prevent these metallic coatings from oxidation, these coatings are protected by a layer of dielectric material.
