Optical and visual inspection verifies transparency, surface uniformity and the absence of optical distortion, inclusions, visual defects and surface imperfections. Qualified operators inspect every component under controlled lighting conditions.

Dimensional checks confirm compliance with the drawing, defined geometries and project tolerances Instrument-based measurements are performed at inspection points established during the sampling phase.

Final testing includes functional verification of the applied treatments, aesthetic inspection of the finishes and completion of the order documentation, with full traceability from raw material to the delivered component.
