Profile projector A profile projector, also known as an optical comparator, is a precision measurement tool used in industries to inspect and measure the dimensions of small mechanical parts. It projects the magnified silhouette of an object onto a screen, allowing for accurate measurement of its dimensions and angles. Ideal for quality control, a profile projector ensures high accuracy in the manufacturing process, making it an essential tool for industries like automotive, aerospace, and engineering that require exacting standards in part production. https://www.optomechengineers.com/optical-profile-projector/
