Nikon iNEXIV VMA 4540

iNEXIV VMA-4540 – Reaching the peak of video measurement

iNEXIV VMA-4540 was launched by Nikon in 2013, coming as an improvement to the previous model. The 450 x 400 x 200mm (XYZ) strokes provide fast measurements for parts with a higher volume and a maximum mass of up to 40 kg. At the same time, due to the large stroke of the axes, several smaller parts can be measured, thus reducing time and costs for this type of operation.

The system is equipped with three types of lighting: episcopic lighting, diascopic lighting and ring LED light source with 8 segments and three angles of incidence, all ensuring the detection of edges with low contrast.  As with the smaller model, the VMA-2520, the touch probe or Laser autofocus module can be optionally mounted. With these options the iNEXIV VMA-4540 measuring machine becomes a complete multi-sensor system.

Benefits & features

Wide field of view and sharp, clear images

The iNEXIV series equipment offers images with a clarity unmatched at any magnification used. A wide FOV of up to 13 mm x 10 mm (at 0.35x) allows easy search and alignment of measuring targets.

Robust 73.5 mm working distance

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

Large XY stroke and long Z stroke

The XY stroke of the VMA-4540 is 450 x 400 mm and is suitable for measurement of large samples and simultaneous measurement of multiple parts. The extended 200 mm Z-axis stroke is ideal for tall workpieces.

Auto Focus with high repeatability

Highly repeatable vision AF offers high-speed, high-precision focusing and height/depth measurement.

Even the bottom of a small diameter hole can be brought into correct focus.

Laser AF (option)

The Laser AF with a long 63 mm working distance is optionally available, enabling height measurement of flat surfaces with high repeatability, in keeping a wide FOV at a low magnification.

Versatile illuminations

Episcopic (top), diascopic (bottom) and 8-segment-ring (with 18-degree oblique angle) LED illuminators enable accurate detection of low contrast edges.

Any 8-segment light can be selected for effective edge detection.

Options for expanding measurement possibilities

The VMA-4540 is touch-probe ready and accommodates optional Renishaw® TP20 or TP200 touch probes to measure 3D shapes parts where vision AF cannot be used. Touch probe and vision measuring are seamlessly switched, since the touch probe works coaxially as the optical axis using dedicated software.

Extended 1.5x high-magnification

Each model can be modified before shipment to extend magnification to 1.5x, powerful enough for precise measurement of minute electronic parts.
