Optical microstructures - Import export

The best known microstructured optic is the Fresnel lens. Compared to a standard lens the surface of the fresnel lens is divided into a number of concentric grooves allowing for a wide range of optical effects (e.g. high-aperture (fast) large-area) while also reducing thickness, weight and cost. Fresnel lenses can be designed as a collimator, collector or with finite conjugates. They are usually corrected for spherical aberration. We offer a variety of standard designs as well as custom designs for our customers. Our lenses can be finished with a range of optical coatings and nanostructures and will be trimmed precisely to our customers requirements.

Surface relief diffusive microstructures (SRDM) are used for specifically distributing light in a defined angle range. They homogenize irregular light distributions as well as local intensity peaks. It is also possible to apply those diffusive microstructures directly into the plano side of all our plastic optics components. Our products will be precily trimmed to our customers requirements.

ORAFOL Fresnel Optics GmbH offers a wide variety of microstructured optical components in varios sizes. Among others fresnel prisms, cylindrical lenses and beamsplitters, lenticular lenses and corner cube reflectors. We provide both a catalogue of standard products that can be adapted to our customers' requirements as well as the capabilities to design and manufacture custom optical solutions including finishing processes e.g. anti-reflective coatings and nano-structures and precise CNC machining.
