VisionGauge® Digital Optical Comparators / Profile Projectors (also known as Shadowgraphs or Video Comparators)

VisionGauge® Digital Optical Comparators / Profile Projectors are the fastest, easiest, most accurate way to compare a part to a CAD file.

Optical inspection sets the standard for part verification in major manufacturing industries in today's high-tech world. We assist leaders in all types of businesses by offering custom automated optical comparators. With the kind of speed, agility, and reliability our systems offer, you’ll be able to compare parts directly to their CAD data and complete inspections and measurements with ease.

About VisionGauge® Digital Optical Comparators

Our VisionGauge® Digital Optical Comparators streamline your manufacturing process by capturing images of manufactured parts and automatically comparing them to their CAD drawings. This means you can reliably confirm a part is within spec or catch production flaws before they go out the door. These systems provide stunning accuracy, necessary in high-demand industries like medical manufacturing, aviation, aerospace, electronics, and pharmaceuticals.

How Can Profile Projectors Benefit Your Business?

VisionGauge® Digital Optical Comparators measure product consistency by comparing parts directly to their CAD file. This process is a quick, highly-accurate way to check for defects and verify all components conform to quality standards.

Digital profile projectors are precise and intuitive, delivering high-quality results in less time than traditional optical comparators. These machines are easy to use, and because they can be fully automated, they operate swiftly and reliably. They also offer a convenient way to streamline inspections, so you can speed up operations, increase throughput, and eliminate operator error.

VISIONx's digital profile projectors offer reports, charts, statistics, and more. In addition to being fully digital, our inspection systems glean data straight from CAD drawings, saving time by making inspections simpler and easier to run. VISIONx's update to traditional optical comparator machines will capture, qualify, and report comparison data at the click of a button. Additional benefits of our systems include:
