Metallic High Reflective Coating

Sinoceramics provides a high reflective metallic coating that is made from Au, Ag, and Al. These coatings which have a consistent high reflection over a wide spectral range are necessary. Their reflectivity is not higher than that of the dielectrics high reflection coating, but the spectrum of the metallic coating can cover the near UV, visible and near-IR. In order to prevent this coating from oxidizing, a dielectric overcoat is used.



R > 95% @ 450 – 11000nm for protected Ag
R > 98% @ 2000 – 12000nm for protected Au
R > 87% @ 400 – 1200nm for protected Al
R > 93% @ 400 – 1200nm for enhanced Al
