| titleOfInvention | Method for improving infrared band transmittance by processing micro-nano structure on chalcogenide glass surface |
| abstract | The invention relates to a method for improving the transmittance of an infrared band by processing a micro-nano structure on the surface of chalcogenide glass, belonging to the technical field of infrared optical glass processing and application. The method directly prepares the micro-nano structure with proper refractive index on the chalcogenide glass surface, avoids introducing new film materials, and solves the problems of the limitation of multilayer film materials and the quality of film layers in the traditional infrared antireflection film plating process; the reactive ion etching adopted in the method is mainly based on the chemical reaction of gas and chalcogenide glass, does not generate any effect on the part covered by the polymer coating, avoids the generation of stress, and is carried out at normal temperature and in a vacuum state, so that the gasification and leakage of toxic components are avoided; the method can also realize the micro-nano structure pattern imprinting of the non-planar surface, expand the range of optical elements for large-area micro-nano processing, and realize the high-efficiency anti-reflection of chalcogenide glass in each infrared wave band by changing the target graphic structure and the process parameters. |
