Actual trends in optical coatings — •Hans Lauth1 and Norbert Kaiser2 — 1JENOPTIK Laser, Optik, Systeme GmbH — 2Fraunhofer Institut Angewandte Optik und Feinmechanik
Optical technologies have essential importance as driving forces of innovations in the markets of the 21st century. They are key technologies which create the conditions for a lot of new developments and their applications in the future. Today, optical coating has been regarded as one of the most important segment in optics technology. It can sufficiently improve the performance of the whole optical system, satisfy the function requirements, and therefore is an intensively active research field worldwide.
Optical coatings can be found in nearly every technical application. Meanwhile, it plays a significant role in many fields development. The efficiency of numerous applications and products in innovative and future technology fields is still limited by the quality of optical coatings. All optical coatings rely on control of nanodimensions. Thus, optical coatings are considered as one of the major enabling technologies for further progresses in many innovative applications.
It is a general trend to use shorter and shorter wavelengths. This trend is strongly driven by the lithography market, but other innovative markets too. The demands lead to the physical limits. This needs basic research in the fields of laser radiation - material interaction, material science, physical, chemical and micro - structural properties of thin films and surfaces. A general progress in the deterministic production is reached in Europe in the last years.
