Benefits and Features


nikon metrology video measuring systems inexiv vma4540 widefovWide FOV (Field-of-View)

The exceptionally wide FOV of up to 13 mm x 10 mm (at 0.35x) allows easy and rapid search and alignment of the measuring targets. With Nikon’s epic 10x zoom optics featuring five specific steps allows precise and accurate measurement as well as high-resolution images. The excellent Apochromat objective lens with high Numerical Aperture  (0.11) and low distortion has been specially designed for the iNEXIV series, providing dimensionally correct and clear images.

* On a 24-inch WUXGA (1920 x 1200 pixels) monitor, recommended for the VMA series.

Robust 73.5 mm working distance

The long 73.5 mm working distance minimizes the possibility of contact between the objective lens and valuable parts. This working distance is ideal for measuring large step heights, tall bosses, deep holes and surface mount components.

The VMA-4540V/4540 is equipped with episcopic (top), diascopic (bottom) and an 8-segment ring (with 18-degree oblique angle) LED illuminators. Combining these illuminators with Nikon’s superior optics provides additional accurate detection of low contrast edges.

Even when a workpiece is misaligned, the video measuring system automatically searches for the correct target location and orientation based on the target image recorded in a teaching file as a base for pattern recognition. This in turn enables the most rapid, accurate and automatic measurements.  Thus eliminating possible detection errors and time delays needing to orient the part.
