The Laser Zentrum Hannover (LZH) will demonstrate what tomorrow’s monitoring of coating processes might look like, in hall 3 at booth A58.

This year, the LZH will focus on three processes: in-situ particle detection; spectral high-resolution online monitoring; and flexible measurement technology.

Especially for longer coating processes, it is important to check optics for defect growth and inclusions during the coating 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 minimise or even eliminate them.

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 fibres.

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.
