For tactile measurements, MCAx supports a wide variety of tactile (straight and hook) and touch-trigger probes in many lengths and stylus configurations.

Intuitive scanning and inspection software

Focus supports intuitive scanning and inspection using an articulated arm or Optical CMM with tactile and/or scanning probes. The software is specifically designed to control data flows with minimum user interaction.

The point cloud builds up in real-time as it is being acquired and is seamlessly followed by inspection of the measured geometry against CAD or another scan.

The Focus inspection toolbox includes advanced analysis functionality such as detailed part-to-CAD comparison, feature extraction, gap & flush inspection and GD&T.

Alternatively, through the Nikon Metrology API, the MMDx/MMCx handheld scanners and MCAx arms can be used directly in many 3rd party inspection software applications, including PolyWorks®, and Geomagic®.

For reverse engineering applications users can select from a broad offering of 3rd party packages which tightly integrate with all Nikon Metrology handheld scanners.


A modular approach to arm mounting and probe connectivity as well as measurement volume extensions and datuming provides a multitude of accessories to enhance usage in the most demanding situations.
