Werth 3D Patch

Focus variation for 3D topography measurement

Benefits

The 3D patch is an area sensor based on the focus variation principle with automatic adaptation of the sensor parameters to the respective surface properties of the workpiece. The optical sensor enables fast 3D nominal-actual comparisons of surface areas or purely dimensional evaluations. With the 3D patch, the topography of even small detailed areas can be measured optically with high lateral resolution.

An HDR function enables the capture of image stacks with different exposure times and the measurement of unevenly reflective surfaces
Intelligent software functions are available for optimal setting of exposure times
A wide range of filter options ensures reproducible and reliable results
Calculation of control geometry elements possible through automatic segmentation

Technical Data

Optical-axial (focus variation)

Permissible probing error up to 0.25 µm

With the hardware of the image processing sensor (a) camera, b) imaging optics, c) measuring object and d) incident light illumination), images are taken in different positions between z1 and z2 on the optical axis. Based on the contrast gradient, many measurement points on the workpiece surface are determined simultaneously.
