Surface Inspection Systems

CVS Trevista X4 - STEMMER IMAGING Ltd.

The fourth generation of CVS Trevista Surface, Cylinder and Multiline surface inspection systems from Stemmer Imaging features brighter illumination to enable faster image acquisition and have a larger measuring field. The new Trevista X4 models utilize a 2.5-D process, called "Shape from Shading," and are especially suited to the examination of components with shiny and diffusely scattering surfaces. Surface defects such as scratches, burrs, dents, discoloration or grinding marks, even if only a few micrometers deep, can be detected with significantly greater certainty with this process than with conventional image processing systems, according to the manufacturer. The X4 generation offers structured, diffuse dome illumination that is brighter by a factor of 2.5 compared with the previous models, enabling faster image acquisition. For a typical image size of four megapixels, evaluation using the Trevista algorithm takes place around 20% faster than before, which results in potentially lower cycle times.
