At the heart of the QVI shapegrabber Ai620 is the brand new sg198 3D scanhead. This blue light laser scanhead incorporates key innovations which allow unprecedented levels of speed, data quality, resolution and dynamic range.
When used at its maximum scan volume, the sg198 scanhead measures data at 155,000 points per second. For parts which do not require the full scan volume, the data rate increases to more than 1.5 million pts/s.
Better Data Quality:
The sg198 scanhead features an optical arrangement that draws on QVI’s 70+ years of experience designing optical systems for precision measurement. The sensor optics provide extremely low noise data that far outperforms other 3D scanning technologies.
The built-in 5MP imager delivers depth resolution and data densities for the most challenging applications. The combination of such high resolution in a relatively large volume makes the entire process of measuring complex shaped parts faster and easier.
Wider Dynamic Range:
ShapeGrabber scanheads offer high dynamic range, accurately measuring a wide variety of materials, colors, textures, and finishes without the need for surface treatments. The sg198 scanhead handles the full range – from matte black plastic, to bare metal, to grainy castings and 3D printed parts.
