Confocal measurement of 1-euro-star 3d and euro.png
The 9th August 2010 is Marvin Minsky's 83rd birthday. He is the inventor of the confocal technology and especially the confocal white light microscopy. When he made his invention in 1957 he probably could not imagine that it once would be a common technology for the measurement of 3-dimensional surface properties in material science.

The picture shows the 3d representation of one of the stars embossed on one side of a 1-euro coin. The size of the measured area is 800 µm by 800 µm (0.8 mm by 0.8 mm), the vertical range is approximately 60 µm (0.06 mm). The colours of the surface show the height according to the scale on the right side of the image.   +/− (lzh), +/− (en)
