Dual-technology surface inspection: 2D Laser + Confocal

High-resolution surface inspection with laser-based technologies for flat laminates, pipes, and profiles.

Surface inspection in the production of flat laminates, pipes and hollow profiles is a crucial aspect to guarantee quality and integrity. Our system combines 2D laser triangulation and laser confocal microscopy for redundant, high-precision measurement, immune to lighting variations and surface reflections.
