Contributions of the Business Unit Optics


Deposition of complex bandpass filters on aspherical lenses

At the Fraunhofer IST a coating process has been developed that enables lenses to be equipped with a narrow bandpass filter at a wavelength of 670 nm, which exhibits a very wide blocking range of 300 to 1100 nm.


Defect-free silicon oxide films

At the Fraunhofer IST film processes will be executed for homogeneous and uniform silicon oxide film of the sphere surface to reduce the degree of measurement uncertainty.


Optical beam splitter

At the Fraunhofer IST outstanding possibilities for the deposition of highly demanding optical coatings were provided with the EOSS® (Enhanced Optical Sputtering System) coating platform. 


Simulation of dust particle movement in a plasma

Via a particle simulation developed at the Fraunhofer IST it is now possible to predict the contamination of dust in plasma coating systems. 


Silicon oxide films with low internal stress

At the Fraunhofer IST, a hot-wire chemical vapor deposition method (HWCVD) has for the first time been evaluated as an alternative production method for SiO2 layers.


Pixel filters

A new combined process for the production of so-called pixel filters has been developed at the Fraunhofer IST, consisting of coating and microstructuring.


Innovative spectrometer

The interference filters required by industry and technology can be manufactured with the aid of thin-film technologies.At the Fraunhofer IST a spectrometer with a smaller angle of divergence has been built.


EOSS® platform

With the development and construction of the innovative coating platform EOSS®, the Fraunhofer IST has created new possibilities for the deposition of highly demanding optical coatings.


Optical interference coating systems

The Fraunhofer IST develops optimized coating processes for optical interference coating systems on polymer films.


PECVD coatings for optical coating systems

A chemical vapour deposition process has been developed at the Fraunhofer IST which allows the mechanical properties of coatings to be varied over a wide range.  


Scratch-resistant antireflective coatings

The Fraunhofer IST has, as part of the EU project “NoScratch”, created antireflective coatings which show minimal abrasive wear even under the most extreme conditions.
