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.
Contract R&D with Microscopy Australia at Flinders University using state-of-the-art confocal Raman microscopy allowed chemical information about surfaces to be determined with sub-micrometre resolution. This technique 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.
