Claim Text:
1. An optical quality control system for detecting a defect in a light permeable high refractive index solid, with a refractive index greater than 1.6, the quality control system comprising: a container configured to receive the solid therein; a structured light source; an optical inspection zone for receiving an optical inspection device or for allowing a human observer to inspect by eye said high refractive index solid received in the container; and a high refractive index medium with a refractive index greater than 1.6 for insertion in the container in a volume sufficient to fully or at least partially immerse the high refractive index solid, wherein the structured light source is configured to project a planar light fan through the high refractive index solid to generate an illuminated cross-section in the high refractive index solid and wherein the optical inspection zone is arranged for inspection of an immersed portion of the illuminated cross-section in an inspection direction transverse to a plane (P) defined by the planar illuminated cross-section, and wherein at least a part of the support structure and the light source transport system are arranged within the container and in that the structured light source is arranged within the container.
