Paper Abstract

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 thickness form center to the edges and hence a spectral shift.
