Applications
The SuperView W1 3D optical surface profilometer is an ideal instrument for sub-nanometer measurements of various precision parts. Based on the principle of white light interference technology, combined with a precision Z-direction scanning module and a 3D modeling algorithm, it non-contactly scans the object's surface and generates a 3D image. After processing and analysis of the 3D image by the XtremeVision software, a series of 2D and 3D parameters are obtained, reflecting the surface quality of the object. The SuperView W1 is an easy-to-use precision optical instrument with powerful analysis functions for all types of surface shape and roughness parameters. Thanks to its unique light source, it can measure various precision parts with both smooth and rough surfaces.

Measurement and analysis of the surface shape and profile characteristics of various products, components and materials, such as flatness, roughness, waviness, appearance, surface defects, abrasion, corrosion, gaps, holes, stages, curvature, deformation, etc.
