Optical element, optical system, imaging apparatus, optical instrument, and stamper

摘要

An optical system includes an optical element that has a surface on which a plurality of sub-wavelength structure bodies are formed; and an imaging device that has an imaging region which senses light via the optical element, wherein the surface of the optical element has one or two or more sections that scatter incident light and generate scattered light, and wherein a sum total of components of the scattered light reaching the imaging region is smaller than a sum total of components thereof reaching regions other than the imaging region.
