MarVisionmm 320 Video Measuring Microscope

Mahr Federal has introduced a new video measuring microscope with image processing capability, the flagship product for a new line of Mahr optical measuring instruments. Designed for the measurement and/or dimensioning of geometric elements, the MarVisionmm 320 incorporates an integrated CCD color camera with zoom lens, a 23" touch screen PC with keyboard and mouse, and easy to use Windows 7-based M3 software. Automatic edge detection allows even low contrast features to be measured, and a Multi Touch function provides quick and continuous variable magnification using either touchscreen or mouse.

"MarVision optical measuring instruments offer a quick and reliable solution to many different 2D measurement and inspection tasks," said George Schuetz, Director Precision Gages for Mahr Federal. "Applications range from cutting tools and precision products for manufacturing, plastics, and medical technology, to miniaturized electronic components. These extremely precise measuring instruments are designed to meet the highest quality and production requirements."

The MarVisionmm 320 rests on a robust hardened granite base with a precision mounted XY table. An optical incremental measuring system assures quick and fine adjustment of the axis, and a laser pointer assists with part positioning. The CCD camera and Navitar Zoom lens with 0.7-4.5x magnification are mounted on a stable Z-column with 200mm vertical movement. Coarse and fine height adjustment knobs are mounted on both sides for precise focusing. Illumination is provided by a quadrant LED ring top light with four individually controlled segments, and table mounted Telecentric LED transmitted light for more focused measurement of rotationally symmetric parts.

The automated video edge detection and multi-touch functions make the MarVisionmm 320 especially suitable for a wide range of punched and flexible parts, plastic components and electronic circuit boards. Measurement and evaluation functions include: Point, such as the intersection of straight lines; Line, including line of best fit and/or centerline; automatic calculation of a Circle, including index and pitch circles; Distance between points or point and line; Angle taken from two lines; and Alignment of axis of the coordinate system on the test piece.
