Coordinate Measuring Machine for Characterizing Conformal Optics

摘要

A Starret PREMIS HGDC 2018-16 direct computer controlled (DCC) coordinate measuring machine (CMM) was purchased and installed in the metrology lab of the Center for Optics Manufacturing (COM) at the University of Rochester. This CMM was a valuable addition to our facility; it allowed for the precise measurement of ground surfaces on a variety of parts generated on the Moore Precision Tools Nanotech 150AG Aspharic Grinder and the Nanotecnnologv Systems Nanotech 5OOFG Freeform Generator. The unique and complex nature of these parts prevented them from being characterized with standard optical metrology instrumentation. The acquisition of this CMM has opened up new opportunities for collaborations with Army programs.
