Optical element in the manner of a linear Fresnel lens and use of the optical element as glare protection from direct sunlight

摘要

The device has a structured front (E) with optically active parts (A) for imaging with the light passing through the element, optically inactive parts (B) for reducing the thickness of the element and a rear side (F). The optically active parts of the surface approximately describe the surface of an asymmetrical single axis lens when taken in sequence and disregarding the inactive parts.
