VisionGauge Digital Optical Comparators by Methods Machine Tools offer the ability to digitally compare a part to its CAD data. This data can also be archived and documented electronically. VisionGauge Digital Optical Comparators will automatically produce an operator-independent “pass / fail” result and display any deviation from specification by comparing a part against bi-directional tolerances at user-specified control points.
VisionGauge Digital Optical Comparators combine the capabilities of an optical comparator, video coordinate measurement machine, machine vision and vision system. The comparators feature an extensive set of machine vision tools to carry out pattern matching, color verification, defect detection and more. A very high resolution imaging system features detailed inspection of subjective properties, such as surface finish verification, digital image collection, annotation and electronic distribution.
VisionGauge Digital Optical Comparators are delivered shop-floor ready, are portable and are also equally suitable for the metrology lab. Fully digital, VisionGauge Digital Comparators collect complete digital records of inspections including images, measurements and other statistical data that are critical for Statistical Process Control (SPC) for documenting quality compliance. Equipped with a barcode reader and joystick interface, VisionGauge Digital Comparators require only minimal operator training.
VisionGauge Digital Optical Comparators feature a high-resolution megapixel digital camera and a low-distortion, wide field-of-view telecentric lens for capturing a high contrast and geometrically precise part image that can be easily viewed in full daylight.
Featuring VisionGauge Online Software, VisionGauge Digital Optical Comparators project high- resolution video images from the camera, along with a digital CAD data “overlay”, on a large quad-monitor display. Systems are offered in a small space-saving footprint of 66" long x 20" wide.
