Abstract: Optical elements including YbF3 layers with high transmittance in the LWIR spectral range are described. The YbF3 layer is produced by an ion-assisted deposition process under high voltage conditions. Dense, uniform, and nearly defect-free YbF3 layers are formed. The improved material quality of the YbF3 layers leads to low absorption in the LWIR spectral range, especially at wavelengths above 10.0 microns. The extinction coefficient of the YbF3 layers is less than 0.0400 at a wavelength of 13.5 microns.

Abstract: Optical elements, optical coatings, and methods of making the same are described herein. In some embodiments, an optical element may include a substrate and a coating. The coating may include a first major surface and a second major surface opposite the first major surface, and the first major surface of the coating may be in direct contact with the substrate. The coating may further include a layer of zinc chalcogenide atop the substrate and a layer of Au atop the layer of zinc chalcogenide. In some embodiments, the coating may further include another layer of zinc chalcogenide atop the layer of Au.
