Nikon Announces New CNC Video Measuring Systems

Nikon Metrology announced two new CNC video measuring systems, the iNEXIV VMA-4540V and 4540. According to the company, the units offer a wide field of view, easy operation, and allow the measurement of both large and tall mechanical parts.

The systems automatically inspect the dimensions of a variety of precision equipment and electric parts, using optical measuring and image processing technologies. By precisely detecting the edges of the sample using CCD camera images and data processing, the measurement of complex sample shapes is possible, the company says.

The VMA-4540V/4540 offers a larger measurement stroke than the iNEXIV VMA-2520, which was released in January 2007. While The VMA-4540V offers video measurement only, the VMA-4540 additionally provides optional touch probe measurement.

The large 450 x 400 x 200 mm stage stroke supports the high-speed measurement of large printed substrates and tall plastic-injection-molded parts, and the mass inspection of multiple parts simultaneously, resulting in a significant reduction in inspection costs.

A wide Field-of-View (FOV) of up to 13 mm x 10 mm (at 0.35x) improves search and alignment of measuring targets. An Apochromat objective lens with high NA (0.11) and low distortion has been specially designed for the iNEXIV series.

The VMA-4540V/4540 is equipped with episcopic, diascopic and 8-segment ring LED illuminators to suit the sample shape. Combining these illuminators and adjusting light intensity and direction, makes the accurate detection of low contrast edges possible.

The series is equipped with highly repeatable vision AF that offers high-speed, high-precision focusing of sample surfaces or edges, reference-plane settings and height/depth measurement. Laser AF is available as an option, enabling the height measurement of flat surfaces with high repeatability at any magnification or depth of focus.
