Faceted gem with improved color disparity and haze reduction

摘要

The incident light enters the facet cut gem, travels along a plurality of optical paths, and leaves the jewel as the outgoing light.At least one diffraction grating is patterned asymmetrically with respect to the symmetry axis.The diffraction grating is disposed at at least one facet and has a diffractive structure that diffracts light along at least one of the optical paths to improve color disparity of the outgoing light.In order to reduce haze of the outgoing light, this diffraction grating is the only diffraction grating to diffract light traveling along at least one optical path.Diagram
