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

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 increased speed, agility and reliability, our systems allow you to compare parts directly to their CAD data while accurately and efficiently completing inspections and digital optical measurements.

Improving Your Operation's Production and Efficiency With 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 ability means you can reliably confirm whether a component is within spec or catch production flaws before they go out the door. These systems provide stunning accuracy, a necessary element in high-demand industries like medical manufacturing, aviation, aerospace, electronics and pharmaceuticals.

How VisionGauge® Digital Optical Comparators Work

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, enabling you to speed up operations, increase throughput, and eliminate operator error.

How a Digital Optical Comparator Can Benefit Your Business

VISIONx, Inc.'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:

Finding the Right System for Your Unique Application

We have multiple digital profile projectors for sale. Our VisionGauge® Digital Optical Comparators use the latest technology and measuring tools to deliver high-quality images, capture reliable data and help you maintain quality control policies. We offer digital comparators in horizontal and vertical configurations to optimize your measuring processes:

  • Vertical digital optical comparators: Vertical models contain a glass insert on the stage for parts placement. Ultra-bright lighting illuminates the part from beneath the glass, displaying the profile for inspection. These designs are ideal for applications involving objects that sit flat on the glass, like plates or other flat-shaped components.
  • Horizontal digital optical comparators: Horizontal optical comparator machines contain an X-axis stage with premium steel, chrome plating and highly durable dovetail mounting grooves for quick and repeatable part placement. The component sits on the stage, perpendicular to the lens and Z-axis. While vertical comparators are ideal for flat parts, horizontal models work well for most other geometries.

If you upgrade an existing optical comparator to a VisionGauge® design, the component's presentation to the camera will remain the same, meaning replacement is easy in the same horizontal or vertical configuration.
