Optical diffusers

Microlens arrays are one- or two dimensional periodic patterns of small lens structures (lens dimensions up to a few millimetres). They can be used in a variety of ways, e.g. collimation or homogenization of light, depending on the design. We offer custom designs for our customers without limitations regarding the pattern in a wide range of lens sizes and overall array sizes. It is also possible to apply a microlens array directly into the plano side of all our plastic optics components. Our products can be finished with a range of optical coatings and nanostructures and will be trimmed precisely to our customers requirements.

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.

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.
