OPTICAL ELEMENT, OPTICAL SYSTEM, IMAGING DEVICE, OPTICAL APPARATUS, AND MASTER AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an optical element capable of suppressing generation of diffracted light, which solves a problem of diffracted light (stray light) when an optical element (such as a lens) having a sub-wavelength structure formed on a surface thereof is used in an optical system, and to provide an optical system, an imaging device, an optical apparatus, and a master and a method for manufacturing the master.SOLUTION: An optical element 11 has a surface provided with a plurality of structures 13. The plurality of structures 13 is disposed at an interval equal to or smaller than a wavelength of visible light and fluctuated in random directions from a lattice point.
