Nikon introduces large-scale non-contact measurement systems

New Laser Radar offers faster measurement, better data quality and improved usability for automated, non-contact, large-scale metrology.

Two new systems for large-scale, automated, non-contact measurement have been introduced by Nikon Metrology. Called Laser Radar MV331 and MV351, the units easily perform repetitive procedures and complex inspection tasks while reducing labour requirements with a host of new features and enhancements. Inspection time is significantly reduced compared to traditional measurement and the systems can be used in a wide variety of applications, including aerospace, automotive and renewable energy.

High-speed vision scans enable faster measurement of complex features, sections and surfaces. New usability features such as an integrated robot mount and removable air filters makes the system even better suited to robotic inspection on the shop floor. In addition to the new, external air filters, positive air pressurisation can be used to keep dust and other airborne particles out when working in harsh manufacturing environments.


Laser Radar delivers true single-person use and supports off-line programming for automated and unattended operation, reducing operating costs. Patented technology enables direct surface and feature measurements at high data rates. As a result, Laser Radar eliminates the need for photogrammetry targets, spherically mounted retro-reflectors (SMRs) and handheld probes. The MV331 also slashes inspection times with high-speed vision scans that capture up to 2,000 points per second, making the unit suitable for scanning complex features and section analysis.

For fully automated, inline or line-side inspections, the Laser Radar can be easily installed on a standard 6-axis robot arm using the built-in robot mounting interface. It is used to position the device automatically so areas can be inspected that are otherwise hidden from the line of sight.

Laser Radar automatically measures alignment points after every move, guaranteeing all measurements are collected in a common coordinate system and ensuring that measurement accuracy is completely independent of the robot.

Users can choose from an array of large-scale metrology software solutions, such as Polyworks, Metrolog and Spatial Analyzer. Flexibility to use third-party software allows customers to use the package of their choice and benefit from the advantages of Laser Radar without having to retrain staff to use new software.
