What is an optical comparator?

An optical comparator is a precision measurement tool that projects a magnified identical image of small parts or objects in order to collect dimension measurements and complete inspection protocols. Also known as a profile projector, an optical comparator makes it possible to take precise and accurate measurements of parts that might otherwise be challenging to work with based on size. Through a scientific magnification process using lights and mirrors, the optical comparator creates a completely comparable and enlarged version of the part. These profile projectors do just that, they project a...
