Applications Seam Inspection: High sampling frequencies and a robust optical construction without any moving parts allow a high temporal and spatial resolution for detecting welding failures. In welding lines product quality can be ensured and optimized. Seam Tracking: The sensitive and at the same time irradiance tolerable sensor enables seam tracking in former problematic applications. With an additional dedicated CNC or robot software a fast and precise 3-dimensional seam tracking is reality. Or in combining sensor and correction axis drive into a self-contained unit an upgrade of existing machines is possible. 3D-Measurement: The profile acquisition along an object either by moving the object or the sensor allows a precise contour or volume measurement e.g. on car bodies, extruded profiles or conveyor belts.
