White-light interferometry for quality assurance
12.03.2009 - Photonik international 1/2009 | [ deutsche Version lesen ]
Quality assurance requirements in the production process are becoming more and more stringent. Optical metrology – including white-light interferometry – is especially well suited to 100% inspection. The technique can be adapted to smooth and rough surfaces, a range of field sizes and resolutions, and also the needed process speed.
