Digital Optical Comparators / Digital Profile Projectors

(PATENTS PENDING)

The VisionGauge® Digital Optical Comparator (Patents Pending) is
The Fastest, Easiest, Most Accurate Way to Compare a Part to a CAD File™

The VisionGauge® Digital Optical Comparator:

Is much more accurate
Is much faster
Has a smaller footprint and uses less floor space
Is much more powerful

... than any other existing optical comparator.

It is:

the only comparator with "Auto Pass/Fail"
the only existing fully digital comparator
the only comparator that can be fully automated

The VisionGauge® Digital Optical Comparator:

Works directly with the CAD data so that no overlay or template is needed
Can collect digital images & records with the CAD overlay and the deviations from nominal
Uses powerful & innovative patent pending technology
Is extremely easy to use
Is shop-floor ready

VisionGauge Digital Optical Comparator

VisionGauge Digital Video Comparators / Optical Comparator Systems display a part's CAD file over live video.

Compared with traditional optical comparators, our VisionGauge® Digital Optical Comparators are competitively priced and offer numerous benefits. Our VisionGauge® Digital Optical Comparators:

Produce a very high contrast image with very sharp edge profiles so that there is no problem viewing it in full daylight
Are much more accurate
Allow the user to be much more productive and get more work done with a single machine
Have "Auto Pass/Fail"
Can compute and display the part's deviation from nominal and compare it to bi-directional tolerances
Work directly with the CAD data so that no overlays / templates / Mylars™ are required
Can be used to collect images (either with or without the CAD data overlay and with or without annotations), measurements and data.
Can also carry out fully automated measurements (like a video CMM)
Can automatically send measurements, statistics and data to Excel™ or other external applications
Have a smaller footprint and use less floor space
Can be moved much more easily and without requiring re-calibration (i.e. "rolling cart" configuration is standard)
Have a much greater optical depth of field, i.e. (everything is in focus all at once)
Have a longer optical working distance (i.e. more clearance between the part and the lens)
Allow you to compare a part to its CAD data beyond the optical field-of-view! (because the CAD data tracks the part and follows the stage motion)
Have LED illumination for very stable illumination over a 10 year life. No more bulbs to change!

Thanks to their advanced patent pending technology, VisionGauge® Digital Optical Comparators are much faster, much more accurate and easier to use than traditional optical comparators.

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 your CAD data.

No More Overlays!

And through their barcode reader and joystick interface, these systems are extremely intuitive and require only minimal operator training. The system can also be setup to allow on-screen measurements, to collect measurement statistics and to save the image of the part with its superimposed CAD drawing, etc, etc, etc...

And because they are fully digital, these systems allow you to collect complete digital records of the inspection and measurement operations.

VisionGauge® Digital Optical Comparators are very robust. They are perfect for both the shop floor and the Quality Control lab.

VisionGauge® Digital Optical Comparators are complete, ready-to-run Windows-based solutions and are delivered network-ready.

They are available in both horizontal and vertical configurations. They have industry standard dovetail mounting grooves for easy part fixturing.

VisionGauge® Digital Optical Comparators are available with transmitted (i.e. back) and / or reflected (i.e. front) illumination. All illumination is LED-based for very stable and repeatable illumination conditions over a very long life (no more bulbs to replace!). Furthermore, the illumination is programmable and computer-controlled. Everything is done through a single simple and intuitive software interface!

VisionGauge® Digital Optical Comparators have power focus & auto-focus!

They are available in industry standard 5X, 10X, 20X, 50X and 100X optical configurations, in either single or multi-mag configurations. Many other configurations are also available. We can configure a system to meet your specific requirements!

An optional high-resolution LASER module is also available for depth & height measurements.

VisionGauge® Digital Optical Comparators are competitively priced and have a very simple yearly calibration procedure that you can carry out yourself.
