Profile Projectors – Accuracy and Calibration

This technical bulletin addresses the accuracy and calibration of profile projectors, also known as optical comparators. No international or American national standard currently exists that addresses the specification of profile projectors. The technical basis for this document is the Japanese national standard on this topic, JIS B 7184:1999. This technical bulletin summarizes the most important technical issues; however, the JIS standard should be consulted for further information.
