What Is an Optical Comparator?

An optical comparator, also known as a profile projector, is a measuring apparatus typically used in the manufacturing industry. Its main function is to inspect, measure, and compare the dimensions of different manufactured parts. Optical comparators use lenses, mirrors, and illumination to project a magnified silhouette of a part. Learn more about what an optical comparator is and how to use it.
