Most Fresnel lenses for projection systems are made from Polymethylmethacrylate (PMMA). Such lenses, e.g. for LCD- projectors, are flat discs whereas one surface is plane and the other microstructured. Special coatings are necessary to reduce stray l

Fresnel lenses for projection optics require a reduction of reflection losses in a wide wavelength and angular range. Their surface relief consisting of inclined microstructures with increasing inclination angle causes a reduction in AR- coating thic

Precise determination of the main refractive indices of biaxial anisotropic coatings is essential for the calculation of their optical performance. Measurements based on wave guiding methods have proved to yield excellent results with these layers. A
