»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
