Werth Laser Probe WLP

Laser distance sensor according to the Foucault principle

Benefits

With conventional triangulation sensors, the measurement result depends very much on the structure and angle of inclination of the surface. This leads to relatively large measurement uncertainties, which only allow the sensor to be used for less accurate measurement tasks. Better results are achieved with the Foucault laser sensor WLP (patented) integrated into the beam path of the Werth Zoom. This is particularly suitable for fast flatness measurements of surfaces tilted by up to 80° or correspondingly curved surfaces.

Due to its special design, the unique Foucault principle of the Werth Laser Probe offers application possibilities that go beyond the limits of typical TTL (Through The Lens) lasers
The WLP is integrated directly into the beam path of an image processing sensor, so that very fast sensor changes are possible
Laser scanning can be easily observed visually during measuring operation
High measuring speed when scanning contours or surface profiles

Technical Data

Optical-axial (Foucault cutting edge)

Permissible probing error up to 0.75 µm

Due to the asymmetry of the laser beam a) through the use of a Foucault cutting edge b), the diffusely reflected light hits different positions of the differential diode c), from which the distance to the workpiece surface d) is determined. Integration into an image processing sensor f) (illumination not shown) takes place via a divider mirror e).
