The Fraunhofer IOF possesses comprehensive expertise in the entire process chain from the design of optical components and systems all the way to system integration. Developments on the basis of this include such as miniaturized imaging and projection systems for information, communication and safety, wafer and mask chucks for lithography and metrology, mirror systems for astronomy and aerospace, laser systems for ophthalmology and materials processing as well as 3D measuring systems for quality assurance, criminology and medicine. The optical components and systems of the Fraunhofer IOF cover the entire spectral range starting from extreme ultraviolet up to terahertz.
