| titleOfInvention | Manufacturing method of fluoride optical element and fluoride optical element |
| abstract | A method for manufacturing a fluoride optical element according to the present invention includes: (I) a step of polishing the surface of the fluoride solid using polishing abrasive grains to form a fluoride optical element; (II) cleaning the fluoride optical element by contacting the fluoride optical element with a fluorine-based gas. According to the present invention, it is possible to efficiently remove trace amounts of polishing abrasive components remaining on the surface of the fluoride optical element, which cannot be removed by the conventional cleaning method, and the composition of the surface portion is almost the same as that of the inside. A method for easily and efficiently manufacturing a fluoride optical element having a smooth and clean surface property and having a very small light absorption loss on the surface even for short wavelength light, and a fluoride optical element. Can be provided. [Selection diagram] None |
