With their precise structure and the flexible manufacturing capabilities of ORAFOL Fresnel Optics the BP and SN diffusers are the ideal solution for illumination without intesity peaks and inhomogen distribution. The surface-relief microstrutures (SRDM) can be implemented directly into the plano-side of Fresnel lenses or other microstructured optics. Through this combination the complexity of optical systems can be reduced without drawbacks in optical respects. 

The diffusive optics can be trimmed to every required shape with low tolerances.
