iNEXIV VMA-4540 - Reaching the peak of video measurement
The VMA-4540V/4540 CNC video measuring system provides a large XYZ stroke and a wide field of view. The touch-probe-ready model VMA-4540 is ideal for a wide variety of industrial measuring applications. The VMA-4540V/4540 is designed for high-accuracy measurement of a variety of work pieces. A wide field of view enables easy confirmation of measurement areas and provides unparalleled operation. Its broader XYZ measurement range, with a longer working distance than ever before, provides ultimate versatility for measurement of both large and tall mechanical parts and uneven surfaces.

Benefits & features
Wide FOV (Field-of-View)
A wide FOV of up to 13 mm x 10 mm (at 0.35x) allows easy search and alignment of measuring targets. The 10x zoom with five specific steps provides accurate measurement as well as high-resolution images. 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.

* On a 24-inch WUXGA (1920 x 1200 pixels) monitor, recommended for the VMA series.
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 measuring range of 450 mm (X) x 400 mm (Y) x 200 mm (Z)
The large 450 mm x 400 mm XY stroke supports measurements of large samples and mass inspections of multiple parts all at once. An extended 200 mm Z-axis stroke is perfect for tall workpieces.
Fast and accurate vision AF (Auto Focus)
The VMA-4540V/4540 series is equipped with highly repeatable vision AF that offers high-speed, high-precision focusing and height/depth measurement.
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.
The VMA-4540V/4540 is equipped with episcopic (top), diascopic (bottom) and 8-segment ring (with 18-degree oblique angle) LED illuminators. Combining these illuminators with superior optics provides accurate detection of low contrast edges.
Even when a workpiece is misaligned, the system automatically searches the target location based on the target image recorded in a teaching file, enabling accurate, automatic measurement by eliminating possible detection errors.
Digital chart comparator
Deviation of contours can be checked by overlaying charts generated digitally from 2D CAD data onto video images. Digital charts always accompany video images.
Touch probe (option)
While the VMA-4540V is only for video measuring, the VMA-4540 is touch-probe ready and accommodates optional Renishaw® TP20 or TP200 touch probes. Touch probes provide measurements of 3D shapes parts where vision AF cannot be used, such as the inner diameter of an oil seal or the clearance angle of an indexable insert. The touch probe offsets from the optical axis, but works coaxially in the same XYZ coordinate system as the optical axis using iNEXIV VMA TP AutoMeasure software.
