Optical Comparators

An optical comparator is a device that applies the principles of optics for the inspection of manufactured parts, specifically as an image dimension measurement system. In a comparator, the magnified silhouette of a part is projected on a screen, and the dimensions and geometry of the part are measured against the prescribed limits. Optical comparators provide a cost effective solution for non-contact measurement. KEYENCE’s range of optical comparator technology provides a fast, accurate and effective method of place-and-press instant measurement technology in product manufacturing.
