»horos« compact optical roughness sensor

Motivation

Stringent demand for surface characterization techniques that are noncontact, fast, compact, and applicable to a wide range of surface qualities – from machined components to optical surfaces.

 

The Sensor

horos (high sensitive optical roughness sensor) is a mobile, light scattering based tool for measuring surface roughness from the micrometer to subnanometer scales.

 

Features

  • Roughness parameters, PSD, 3D scattering distribution, isotropy etc.
  • Sensitivity: Rq < 0,5 nm
  • Measurement time: < 1 s
  • Direct link to profilometric techniques

 

Applications

Quality control for

  • Plane and complex (freeform) surfaces
  • Optical fabrication (surface-finishing, coating, molding etc.)
  • Mechanical engineering
  • Automotive industry
