Optical comparator - Wikipedia
https://en.wikipedia.org/wiki/Optical_comparator
WEBAn optical comparator (often called just a comparator in context) or profile projector is a device that applies the principles of optics to the inspection of manufactured parts. In a comparator, the magnified silhouette of a part is projected upon the screen, and the dimensions and geometry of the part are measured against prescribed limits .

What Is an Optical Comparator and How Does It Work?
https://www.visionxinc.com/what-is-an-optical-comparator
WEBOct 21, 2020 · Optical comparators are used to check for both dimensional accuracy and surface defects, such as scratches and indentations. In short, they allow for non-contact measurement and observation, minimizing handling while still allowing for close inspection. There are two primary configurations of optical comparators: horizontal and vertical.
