VisionGauge Digital Optical Comparators

VisionGauge® Digital Optical Comparator / Profile Projector systems allow you to quickly, easily and very accurately compare a part with its CAD DXF 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! 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 transparencies
* The time required to calibrate the transparencies (and verify this calibration)
* Using transparencies (instead of the direct CAD data) necessarily introduces an error when printing the part’s drawing onto the transparency (no printer is perfect). Using the CAD data directly completely eliminates this error.
* Transparencies can tear, get damaged, stained, worn, etc… CAD data, on the other hand, is digital.
* Transparencies need to be physically stored & retrieved. This takes both time & storage space and transparencies can only be used by one person at a time. CAD files are available whenever you need them, on the hard disk or across the network. CAD files can also be shared, copied, etc…
* Setting up transparencies is a slow and very operator-intensive process. Reading-in a CAD file is almost instantaneous.
* It’s impossible to “recall settings” for a transparency (i.e. position & orientation). The operator needs to re-align every time that he sets up a part. But with a CAD file, “settings recall” is automatic!

Because they work directly with the CAD data, instead of transparencies, VisionGauge® Digital Optical Comparator systems completely eliminate all of these problems!

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

And through their barcode reader and joystick interface, these systems are extremely intuitive and require only minimal operator training. The system can be setup so that when the operator scans the part’s barcode, the correct CAD drawing is automatically read-in. The operator then uses the joystick to align the drawing with the part and presses either the PASS or FAIL button. 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…

VisionGauge® Digital Optical Comparator systems are perfect for both the shop floor and the Quality Control lab.

They are available in both horizontal and vertical configurations, with and without motorized stages and 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.

VisionGauge® Digital Optical Comparator systems are available in both desktop and “rolling cart” configurations.

Many other configurations are also available.
