Metallic Reflection Coatings



Metallic coatings are used for very broad bandwidth reflectors. These coatings are very soft and usually require a protective dielectric overcoat as they are easily susceptible to scratches. The metallic coatings are non
sensitive to polarization and incident angle and are usually used for low power applications, due to the lower damage thresholds.
