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-to-part deviation analyses 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 image stacks to be taken with different exposure times and the measurement of unevenly reflective surfaces
Intelligent software functions are available for the 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

The hardware of the image processing sensor (a) camera, b) imaging optics, c) measuring object and d) incident light illumination) is used to capture images in various positions between z1 and z2 on the optical axis. Based on the contrast curve, many measurement points on the workpiece surface are determined simultaneously.
