What surface defects can LGE surface inspection detect?

LGE systems detect scratches, pits, pinholes, stains, oil contamination, roll marks, edge cracks, chatter marks, dents, bruises and coating defects on flat laminates, pipes and profiles.

What roughness parameters are supported?

The system computes Ra, Rz, Rq, Rt, Rsk and Rku, plus areal roughness metrics and full profile analysis with sub-micron resolution.

Which technologies are combined in the LGE surface inspection system?

The system combines 2D laser triangulation scanning (up to 64 kHz, 3200 points per profile) with chromatic confocal microscopy for sub-micron axial resolution, and an AI fusion engine to produce a complete 3D surface model.

Is the inspection immune to lighting variations?

Yes — because the system is laser-based rather than camera-based, measurements are immune to ambient lighting and surface-reflectivity variation, which makes it suitable for reflective metals and coated surfaces.
