iNEXIV VMA Series – Optical & Tactile Coordinate Measuring System
With a large field of view, a long working distance and large XYZ strokes, the iNEXIV VMA series offers the ultimate in usability for automatic measurement of 3D components.
Various Measuring Applications with a Wide FOV
The iNEXIV VMA series provides three types of measurement envelope together with wide field of view optics. These touch probe-ready systems are ideal for a wide variety of industrial measurement, inspection and quality control applications using both vision and tactile measurement.
The VMA series is optimised for speed and ease-of-use as well as repeatable, accurate measurement of a variety of different components.
Product Highlights
Long Working Distance
The iNEXIV VMA has a long working distance of 73.5mm. It is well suited to depth measurements where the height variation is large, such as on high bosses and in fine, deep holes.
Tactile Measurement (option)
The iNEXIV VMA is able to measure the dimensions and angles of non-visible features, such as holes on the side of a component.
Core Features
Nikon Optics Provide Sharp Clear Images
The Nikon 10x zoom optical system with five specific steps provides accurate measurement as well as high-resolution images. An excellent objective lens with high NA (0.11) and low distortion has been specially designed for the iNEXIV series, providing crisp, clear images.
Touch Probe for Measurement of Features Which are Not Visible
The iNEXIV VMA series can accommodate optional Renishaw® TP20 or TP200 touch probes. Touch probes provide measurements where vision probes or vision autofocus cannot be used.
