VisionGauge® http://www.visionxinc.com/optical-comparators-profile-projectors/about-digital-optical-comparators.html" target="_blank">Digital Optical Comparator / Profile Projector systems allow you to quickly, easily and very accurately compare a part with its CAD drawing.

And while traditional optical comparators require an overlay (i.e. a template or transparency), with the VisionGauge® Digital Optical Comparator everything is done electronically so that there are no more templates! You will never again have to buy, print, calibrate, verify, identify, trace, manage, and physically store & retrieve another template. No more template-related costs, delays or errors. The VisionGauge® Digital Optical Comparator works directly with the CAD data.

These very easy-to-use systems include a high-resolution Megapixel digital camera and a low-distortion, wide field-of-view telecentric lens and produce a very high-resolution, undistorted digital image with a large depth of field.

VisionGauge® Digital Optical Comparator systems also include our powerful and easy-to-use VisionGauge® OnLine software. VisionGauge® OnLine projects the video images from the camera, along with the part’s CAD overlay, in real-time, on a large quad-monitor display. This allows you to view the system’s crisp & clear images in full resolution and to make out very fine details.

The VisionGauge® OnLine software scales the CAD drawing very accurately to match the system’s optical magnification. This is all done completely automatically, in real-time, and requires absolutely no operator intervention.

The operator can use an external 3-speed joystick to align the CAD drawing with the part (for both rotation and X,Y position). This is a very fast and intuitive way to align the part and its CAD drawing. An on-screen joystick is also available.

With our VisionGauge® Digital Optical Comparator systems you can see, right away, if a part matches its CAD definition. There is no setup or calibration time when you want to inspect and measure a new part.

Our VisionGauge® Digital Optical Comparator systems also provide all of the benefits of having a digital image of the part, with its superimposed CAD drawing. You can save the image, carry out fast and accurate on-screen measurements, annotate the image, email it to a customer or a supplier, database the images and the measurements along with other data, etc...

Traditional optical comparators are subject to the following shortcomings:

• The cost of the transparencies
• The cost and maintenance of the equipment required to print the transparencies
• The cost and maintenance of the equipment required to calibrate the transparencies
• The time required to print the trans
