The fascination of microstructured surfaces
A surface is not just a surface. Microstructures can add or modify optical properties of a surface and thus fulfil many different functions.
 Antireflection and antiglare for computer displays |
| Holographic diffusers for light shaping |
Diffraction gratings for measurement systems, holographic
 security devices and packaging material |
Micro-optical structures like prism-arrays for lighting and
day-lighting applications (see project "Mikrofun") |
Also non-optical effects such as modification of wetting properties, adhesion or friction on the surface can be achieved.
The great economic advantage of microstructured surfaces lies in their manufacturing using mass-replication processes such as injection moulding or continuous film replication.

Who we are and what we do
Our business is the design and the realisation of functional surfaces for light management and other applications. Holotools was founded in 2001 by engineers and scientists of the Fraunhofer Institute for Solar Energy Systems. Extensive technological know-how has been developed in micro optics, lithography processes, micro patterning techniques and optical design. A strong focus has been set on the realisation of uniform microstructures on large areas without any seam lines - the key success factor for the commercial use of microstructures in many applications.
Holotools uses this technology, called interference lithography, to produce embossing tools for customers who transfer the structures into polymer products. Holotools is the only company in the world producing sub-wavelength antireflection structures on areas of up to 36" diagonal with the performance, the uniformity and the cosmetic quality required to be used in commercial production. This is just one of many examples demonstrating Holotools' world-wide leading edge position.
