What tomorrow’s monitoring of coating processes might look like will be presented by the Laser Zentrum Hannover e.V. (LZH) at the Optatec 2018 in Frankfurt/Main from May 15th to 17th, 2018, in hall 3 at booth A 58. This year’s three focuses of the LZH are: in-situ particle detection, spectrally high-resolution online monitoring and flexible measurement technology.

Especially for longer coating processes it is important to check the optics for defect growth and inclusions during the process. The LZH develops systems for in-situ particle detection, which can be used to control complex coatings. These make it possible to identify sources of contamination in the process and to minimize or even eliminate them.

Spectrally high-resolution online monitoring and flexible measurement technology
Complex multi-layer systems with the highest spectral requirements call for a high-resolution layer thickness monitoring in order to be able to meet the specifications. The LZH is working on online monitoring systems that also meet future resolution requirements. Likewise, the LZH is researching a flexible measurement technology for quality control even for small optics and fibers.

At the trade fair, the LZH will continue to offer its expertise and advice in the area of coating and process development. These include optics for space applications, astronomy, laser applications and lighting technology.

Laser Zentrum Hannover e.V. (LZH)

As an independent, non-profit research institute, the Laser Zentrum Hannover e.V. (LZH) stands for innovative research, development and consulting. The LZH is supported by the Lower Saxony Ministry for Economics, Labour and Transport and is dedicated to the selfless promotion of applied research in the field of photonics and laser technology. Founded in 1986, over 170 employees are now working for the LZH.

The focus of the LZH lies on the fields of optical components and systems, optical production technologies, and biomedical photonics. Interdisciplinary cooperation between natural scientists and mechanical engineers makes innovative approaches to challenges from the most different areas possible: from the development of components for specific laser systems to process developments for the most diverse laser applications, for example for medical technology or lightweight construction in the automotive sector. Nineteen spin off companies have emerged from the LZH up to now. Thus, the LZH has created a strong transfer between fundamental science, application oriented research, and industry.
