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


Nikon Metrology introduces the new MV331 and MV351 for large scale, automated, non-contact metrology. The new Laser Radars easily perform repetitive procedures and complex inspection tasks whilst reducing labour requirements with a host of new features and enhancements. The Laser Radar’s high speed ‘vision scans’ enable faster measurement of complex features, sections and surfaces. New usability features such as an integrated robot mount, removable air filters and improved measurement stability makes this system suitable for robotized inspection on the shop floor. The new Laser Radar slashes inspection time compared to traditional measurement systems and can be used in a wide variety of applications including aerospace, automotive, renewable energy and more.

Premium productivity for large volume inspection

The Laser Radar’s patented technology enables direct surface and feature measurements at high data rates. As a result, the Laser Radar eliminates the need for photogrammetry targets, spherically mounted retro reflectors (SMRs) and handheld probes. The MV331/351 also slashes inspection times with high speed ‘vision scans’ that capture up to 2,000 points per second, making the Laser Radar ideal for scanning complex features and section analysis. For manual measurements, the multi-zoom overview camera allows the operator to easily locate the target part within a larger workspace. The camera can then zoom in on the features that need to be inspected, to accurately position the measuring laser without even going near the part.

Designed for accurate feature inspection

Correctly manufactured geometric features are critical for high-quality assembly and part mating. The Laser Radar can automatically perform feature, edge and trim measurements; improving product quality. With the Laser Radar, feature inspections are much faster than traditional methods and can be completely automated – without the need for an operator during runtime. The Laser Radar’s edge detection tools also allow users to measure both sharp and hemmed edges with superior accuracy.

Existing inspection stations can be easily converted to measure with the Laser Radar  as it can directly measure traditional tooling like tooling balls, photogrammetry dots, trihedrals or even reflective tape. In addition, the Laser Radar’s unique ability to precisely measure through mirrors allow it to see round corners and to measure occluded geometry.

A redesign of the internal components and improved environmental control increases measurement stability. Some direct advantages of this include longer periods between calibrations and less measurement susceptibility due to environmental factors. This allows the Laser Radar to run a full day between field checks, even in a manufacturing environment.

Flexibility in measuring surfaces and finishes

Recapturing one billionth of the reflected laser beam is enough for the Laser Radar to accurately perform a measurement. This means the Laser Radar can scan dark diffuse as well as highly reflective materials or surface finishes of any colour at sharp incident angles. The system’s high signal/noise ratio yields repeatable range measurements on composites, metals and even highly reflective painted surfaces. The non-contact measurement technology also makes the Laser Radar ideal for measuring hot, soft or delicate surfaces.

Ready for shop floor use

For fully automated inline or line-side inspections, Laser Radars can be easily installed on a standard 6-axis robot arm with the built-in robot mounting interface. The MV331’s interface provides a stable mount for a large rage of industrial robots. The robots are used to automatically position the Laser Radar so it can then inspect areas otherwise hidden from the line of sight. The Laser Radar automatically measures alignment points after every move, guaranteeing all measurements are collected in a common coordinate system and ensuring the measurement accuracy is completely independent of the robot.

The Laser Radar’s serviceability is improved with external air filters that are easily replaceable, with no need to remove the Laser Radar from the mount. In addition to the new filters, positive air pressurization can be used to keep dust and other airborne particles out when working in harsh manufacturing environments.

Seamless integration with common large scale metrology software

Customers can choose from a host of large scale metrology software solutions or use the software SDK to directly control the Laser Radar. Spatial analyzer, polyworks and metrolog software are all commonly used in conjunction with Laser Radar. This flexibility in 3rd party software allows customers to use the software of their choice and benefit from the advantages of the Laser Radar without having to re-train on new software. The Laser Radar comes with an easy-to-transport, small footprint cabinet including a high-performance PC and peripherals.
