Handheld laser scanner introduced

Incorporating blue laser technology, a fast frame rate, specially developed optics and the ability to measure challenging materials, ModelMaker H120 is the next generation of portable laser scanners from Nikon Metrology. The system offers a field-of-view width up to 120 mm and a point resolution down to 35 μm. A frame rate of over 450 Hz is available even when measuring difficult surfaces such as carbon fibre and gloss black, as well as reflective or multi-coloured parts.
With 2000 points per scan line and no reliance on point-to-point interpolation to artificially boost data density, it is possible to measure very small details on large surfaces even when cycle time is critical, says Nikon.
ModelMaker H120 uses advanced optics and a blue, low-speckle laser to generate high-accuracy, low-noise data, making it possible to identify small surface scratches and abrasions. In addition to rapid collection of surface data, sharp edges are represented with clarity thanks to a scanner accuracy of 7 μm and a combined system accuracy with Nikon Metrology’s MCAx articulated arms of up to 28 μm.
The fourth generation of the company’s Enhanced Sensor Performance (ESP4) adapts the laser source intensity, not just for every scan line, but for every point in each scan line, enabling parts with significant colour changes or reflectivity to be measured from any angle. This minimises the need for training, as a single-scanner setting is capable of measuring almost all parts encountered in industrial metrology applications, says Nikon.
