New iNEXIV VMA-4540 video measuring systems for precise inspection of larger samples


Nikon Metrology is pleased to announce 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. The new iNEXIV VMA-4540 CNC Video Measuring Systems will be presented at the CONTROL 2014, the international trade fair for quality assurance.

nikon metrology vma 4540iNEXIV 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, that was released in January 2007. While The VMA-4540V offers video measurement only, the VMA-4540 additionally provides optional touch probe measurement.

Suitable measuring range for large parts of or multi-part inspection

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.

Clear images with wide field of view

A wide Field-of-View (FOV) of up to 13 mm x 10 mm (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 has been specially designed for the iNEXIV series, providing 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.

Fast and accurate vision Auto Focus (AF)

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.

Tactile 3D shape measurement (option)

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 cannot be used, such as lengths and angles in areas that cannot be seen from above.

Video and touch probe measurement can be easily combined using a single teaching file.

The iNEXIV VMA-4540V/iNEXIV VMA-4540 CNC Video Measuring systems are available from April 1, 2014.
