Abstract: A method for manufacturing a spectacle lens and a related technique thereof, includes: performing desired marking processing by irradiating one surface of a spectacle lens with laser, the spectacle lens having an object-side surface and an eyeball-side surface each having a different anti-reflection film, the marking processing including: determining an applicable wavelength of the laser to be used; selecting a surface with an anti-reflection film having a relatively low reflectance to the applied wavelength, out of the object-side surface and the eyeball-side surface; and performing laser irradiation to the selected surface using the applied wavelength.

Abstract: Provided is a technique by which an optical member is marked without degrading the quality of the optical member. The optical member is produced through a removing step (S108, S113) of partially removing a low refractive index layer, which is the outermost layer of a multilayer structure in which the low refractive index layer and a high refractive index layer are layered on each other, by performing non-heating processing on an antireflection film that is formed to cover an optical surface of an optical base member and has the multilayer structure, through irradiation with an ultrashort pulse laser beam so as to expose the high refractive index layer.

Abstract: Provided is an optical component or the like having a stealth mark that is invisible under visible light and is visible under light of a predetermined wavelength. An optical component includes a stealth mark that is invisible under the visible light and visible under the predetermined wavelength, and the stealth mark includes an impregnated region formed from a fluorescent coloring material, and the stealth mark is integrated into the optical component such that an outermost surface of the stealth mark is flush with a surface of the optical component.

Abstract: A film forming step of forming a thin film on an optical surface of an optical substrate, the optical surface having a curved surface shape, and a removal step of partially removing the thin film on the optical surface to perform patterning of the thin film. In the removal step, the thin film is removed by being irradiated with a laser beam.
