TopMap Micro.View+ - the innovative high-end optical profiler by Polytec opens up entirely new possibilities regarding topography and surface texture measurements. This presentation introduces the advanced world of nature-made microlens arryas (on bent surfaces) using this new CSI microscope. An experimental physicist talks about his intuitive approach demonstrating the operational performance of this new product and the resulting opportunities for scientists and future end-users exemplified by Drosophila’s compound eye. We will look at changing patterns in compound eyes, the number of ommatidia, and the facet diameter.
