optical comparator Insights

What is optical comparator?

An optical comparator, also called a profile projector, is a device that projects a magnified image of a part onto a screen for measurement and inspection. It is commonly used in manufacturing and quality control to compare the dimensions of a manufactured part to its specifications, detect surface defects, and measure angles and other geometric features. It uses principles of optics to magnify a part's silhouette.
