Traceable optical roughness measurements with the Alicona roughness standard 

Provable precision of optical roughness measurement  

The roughness standard of Alicona is a verified standard to trace back optical roughness measurements. It is used to verify roughness measurement results performed with the optical 3D surface measurement device InfiniteFocus. Developed by Alicona, the roughness standard is traceable back to the PTB. This is how the precision of the optical technology Focus-Variation is verified. This standard does not only apply to the 3D measurement systems of Alicona. It is applicable to all ISO classified optical measurement methods.

Prove accuracy of optical roughness measurements

  • with the roughness standards users prove accuracy of the optical form and roughness measurement device InfiniteFocus
  • the measurement standard is applicable for tactile and optical methods
  • the roughness Ra, Rq, Rz… is measured via profile measurement
  • the common practice of performing traceable optical measurements with a standard of the tactile equipment category is not necessary anymore

Roughness and form measurement devices of the InfiniteFocus line

The roughness standard as well as the verification tool both verify the measurement accuracy of the InfiniteFocus product line. The measurement systems of the InfiniteFocus line are roughness and form measurement devices for quality assurance in the lab and in production. All measurement systems work within the area based technique Focus-Variation. The InfiniteFocus product group comprises the standard measurement system InfiniteFocus and a series of industry specific variants:

3d micro-coordinate measurement technique for roughness and form measurement

Alicona offers optical 3d surface measurement systems for quality assurance in research and production. Core competence is the measurement of roughness and form also across large measurement areas and volumes. The cutting edge measurement and the measurement of small radii and angles are typical applications. Focus-Variation, the core technique of the InfiniteFocus line, combines the traditional surface metrology and the micro coordinate measurement technology. This technology achieves traceable and repeatable results in highest resolution even in production.
