• Optical components play an important part in many modern devices, ranging from miniature cameras to mobile phones and medical applications such as endoscopes to high-performance optical sensors of ever-decreasing size in industry and robotics.

    In all optical applications, the commonly occurring yet detrimental reflection of light is still a problem. These reflections make images appear darker, interfere with the optical path, produce „ghosting“ and can even seriously damage devices in certain laser applications. In order to reduce these undesirable reflections, thin film anti-reflective coatings have been used up to now. These very thin layers of special materials are however only effective within very small wavelength ranges and have a relatively low mechanical strength and durability.

    Some insects have had the solution to this problem for millions of years. On the surface of a moth’s eyes for example, miniscule, conical nanostructures ensure an almost complete absence of reflection.

    The newly-developed nanoAR process makes affordable production on a large scale possible. Applications includes lens and optical sensing systems, touchscreen displays and devices, spectroscopy systems, microscopy, medical devices, spectroscopy, light extraction and light harvesting devices, illumination, sensor and communication sensor technology.

    „Man kann was man will“. The Lothar-Späth-Award was presented in Stuttgart in remembrance of the straightforward credo of the former Prime Minister of Baden-Württemberg, Prof. Dr. h. c. Lothar Späth. The prize, first announced in 2018, went to three cooperative innovations from industry and science. In front of 300 invited guests, the prizewinners from Baden-Württemberg and Thuringia received a total of 40,000 euros in prize money for particularly future-oriented projects. Among the prizewinners was Nanopta led Dr. Zhaolu Diao. They received the 2nd prize together with innovation partners Prof. Dr. Robert Brunner (Ernst Abbe University Jena) and Prof. Dr. Joachim Spatz, Director at the MPI for Medical Research.


    nanoAR takes nature as its role model. Nanopta GmbH and its innovation partners, the Ernst Abbe University in Jena and the Max Planck Institute for Medical Research in Heidelberg, were honoured for the development of biomimetic nanostructures for high-performance optics. The eyes of nocturnal insects are designed in such a way that they practically do not reflect incident light. With nanoAR technology, the prizewinners have developed a method for synthetically producing such a structure and applying it to surfaces. These tiny nanostructures reflect optical components and enable very high optical quality, which is important for laser systems in production, for medical diagnostic or therapeutic instruments, for optical sensors or for high-quality photo systems. „There are still many secrets in the world that we want to unravel in order to master the challenges of the present. One of them has now been unveiled,“ said Dr. Daniela Späth-Zöllner, member of the jury and daughter of Lothar Späth, praising the excellent project.


    Nanopta was founded in 2018 by the participating researchers with the aim of commercialising the nanoAR technology. With its focus on high-end photonics applications, Nanopta targets a branch of industry that occupies an outstanding position in Baden-Württemberg and Thuringia (microscopy, endoscopy, sensor technology, laser material processing, lithography for the semiconductor industry, optical systems for mobility and safety).


    The Lothar-Späth-Award-Foundation is offering the Lothar-Späth-Award in the federal states of Baden-Württemberg and Thuringia, which honours the work, pioneering achievements and exceptional personality of Prof. Dr. h. c. Lothar Späth in business, politics and society (
