optical comparators Insights

What is optical comparators?

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 and shapes of parts against a master or known standard, identify defects, and ensure parts meet specifications.
