Research and Development Competence Center for Optical Coating and Characterization

Design, manufacture and characterization of complex, high-quality coatings such as

  • steep filter characteristics with highly complex coating design
  • reproducible ultrathin ITO layers
  • coating process development for 2D materials

Combination of optical coating with measurement technology and analytics!

Characterization Center with unique measurement equipment for low-loss coatings, surfaces and broad-based analyses of individual optics

Unrivalled expertise in ultra-precision manufacturing and optical coating at one location


Optical coating

Optical coating processes to produce materials and components faster and more cost-effectively, and coatings with properties not previously achievable via conventional processes, can give companies a decisive competitive edge. 

The Optical Coatings division at RhySearch develops and conducts research for the benefit of the optics industry. Our employees have many years of research and industrial experience in the field of optical coating. Thanks to their competences and our unique technical infrastructure, we are able to cover a wide range of topics in the field of coatings, characterization/analysis and surface treatments. The scientific and technological strength of our laboratory is based on these three core topics.

Our research activities focus on the production of next generation optical coatings. For this purpose, we investigate a variety of aspects along the entire process chain. Our core competencies are continuously strengthened through collaborations with other national laboratories, industry and academia representing the forefront of research in this field.

Annually, RhySearch organizes together with OST, Fraunhofer IOF and Swissphotonics the OCLA Symposium.

Coating technology

  • Ion beam sputtering (IBS): broadband and single wavelength optical monitoring
  • Atomic layer deposition (ALD): thermal and plasma processes
  • Flexible research facility: combination of IBS, pulsed laser deposition, ion beam etching, laser treatment
