Dielectric Coating-HR Coating And PR Coating

Dielectric Coating-HR Coating And PR Coating

A dielectric coating consisting of alternating layers of quarter-wave film of a higher refractive index and lower refractive index than the substrate. Such coatings can be made very specific to a reflected wavelength by varying the layers’ thickness or film indexes, spread over a wide wavelength interval including high reflection coating (HR) and partial reflective coating (PR).
