Measuring table for optical coordinate measuring machine

摘要

The measuring table (1) has a support surface (3) for the measured object (2) formed from a number of relatively spaced transparent plates (6,7), with a light source on one side of the support surface and a measuring device on its opposite side. The hollow space (9) between the transparent plates is hermetically sealed and filled with a compressible transparent pressure medium at a higher pressure than the ambient air.
