Eyeglass lenses, diffractive optical elements, diffractive optics and optical instruments

摘要

Spectacle lens including a diffractive optical element, and a second optical element component having a first optical element element having a diffractive optical surface of the first diffractive optical surface of the second. The second optical element component and the first optical element component, and is disposed between the diffractive optical surface and the second diffractive optical surface of the first so as to face each other. Of the diffracted light of the diffraction orders of multiple generated by the diffractive optical element, the focal position of the diffracted light of the following number of any adjacent is away 0.5D (m ^-1) or more.
