Optical layers for fresnel surfaces

Optical layers for fresnel surfaces

An optical element includes a Fresnel surface including valleys between Fresnel segments. Compensation trenches disposed in the valleys are configured to accept excess of an optical layer received in the valleys during a deposition of the optical layer. The compensation trenches are filled with the...
