Carl Zeiss Vision (Germany) / Flinders University

Problem: Ophthalmic lenses are generally coated with a number of different functional layers. For the development and manufacturing of such optical layer stacks, it is crucial to get detailed information about the chemical composition of the layers and possible artefacts that may occur during processing.

Solution: State-of-the-art confocal Raman microscopy has allowed chemical information about surfaces to be determined with sub-micrometre resolution. This technique has established the chemical composition of a number of optical layer stacks on ophthalmic lenses provided by Carl Zeiss Vision. This helps Carl Zeiss Vision to further optimise their coating processes and to guarantee consistently high product quality and performance.
