iNEXIV VMA-4540V and 4540 CNC Video Measuring Systems

March 01, 2014

Nikon Metrology announces two new CNC Video Measuring Systems, the iNEXIV VMA-4540V and 4540. These products offer a wide field of view, easy operation, and allow the measurement of both large and tall mechanical parts. iNEXIV CNC Video Measuring 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 cost-effective VMA-4540V/4540 is an addition to the iNEXIV series. It offers a larger measurement stroke than the iNEXIV VMA-2520. While The VMA-4540V offers video measurement only, the VMA-4540 additionally provides optional touch probe measurement.

The large 450 x 400 x 200mm 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 13mm x 10mm (at 0.35x) makes the search and alignment of measuring targets easy. An excellent Apochromat objective lens with high NA (0.11) and low distortion, designed especially for the iNEXIV series, to reportedly provide crisp, clear images. 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 VMA-4540V/4540 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. Non-contact measurement using vision AF has the benefit; it does not damage or deform parts. Laser AF is available as an option, enabling the height measurement of flat surfaces with high repeatability at any magnification or depth of focus.

The VMA-4540 is touch-probe ready and can accommodate optional Renishaw TP20 or TP200 touch probes. Touch probes enable the measurement of 3D parts when video measuring methods are unable to inspect lengths and angles in areas that not visible from above. A single Teaching File captures both video measurements and touch probe measurements into one.
