Optodigital Microscopy Enhances Efficiency of Material Testing
Automated microscopes can help speed up the industrial quality-control process, saving time and money. Time is money when it comes to industrial work flows, and efficiency is a key priority. This is especially true with regard to one of the SGS Institute’s most recent projects: quality control of carbon-fiber reinforced polymer (CFRP) parts for the new BMW i3 electric car, which has since gone into production. The Geneva-based SGS Group offers testing and certification of a wide
