Latest Patents

Robert Chow holds a patent for "Optical coatings of variable refractive index and high laser-resistance." This innovation involves the creation of variable index optical single-layers, optical multilayers, and laser-resistant coatings made from a perfluorinated amorphous polymer material through physical vapor deposition. The process utilizes materials like bulk Teflon AF2400 to form thin layers with a very low refractive index, ranging from approximately 1.10 to 1.31. These coatings are highly transparent across the ultraviolet to near-infrared spectrum and maintain the low refractive index characteristic of the bulk material. The refractive index can be adjusted by varying either the deposition rate or the substrate temperature. These coatings are particularly useful in anti-reflectors, graded anti-reflection coatings, and optical layers for laser-resistant applications at wavelengths below 2000 nm.
