Abstract

TITRE: ENDOSCOPE POUR LE CONTRÔLE DE RESSUAGE PAR MESURE SOUS UV L’endoscope (1) selon l’invention comprend un tube rigide (10) contenant des moyens de guidage de lumière UV et de transmission d’image, un adaptateur (2) comprenant une pige (3) de dimensionnement amovible et disposée en vis-à-vis de la lumière UV, il est caractérisé en ce que la pige (3) de dimensionnement réfléchit la lumière UV. La pige est ainsi facilement visible et éclairée en même temps que le défaut, ce qui permet un ajustement plus précis. Figure à publier avec l’abrégé : Figure 3TITLE: ENDOSCOPE FOR MONITORING BY MEASUREMENT UNDER UV The endoscope (1) according to the invention comprises a rigid tube (10) containing UV light guiding and image transmission means, an adapter (2) comprising a removable sizing rod (3) arranged facing the UV light, it is characterized in that the sizing rod (3) reflects the UV light. The pin is thus easily visible and illuminated at the same time as the defect, which allows a more precise adjustment. Figure to be published with the abstract: Figure 3
