Abstract

Technoscope pour observation circulaire, se composant d'un système optique à lentilles ou à fibres optiques pourvu d'un conducteur de lumière à fibres, qui entoure cylindriquement le système optique. Il est prévu, en avant de l'extrémité distale du conducteur 4 de lumière à fibres, un anneau cylindrique 9 en verre entourant l'extrémité distale du système optique 1, 2, 3 et produisant une dispersion diffuse de la lumière et, en avant de l'extrémité distale du système optique, un réflecteur fixé à l'aide d'une monture 10 sur l'extrémité distale du système optique ou du conducteur de lumière, à savoir un prisme conique dont le sommet est dirigé vers le système optique, ou bien un corps 12 sphérique ou cylindrique en verre, dont la surface distale comporte un évidement 13 conique ou sphérique, formé par meulage, servant de réflecteur et disposé symétriquement par rapport à l'axe du système optique. Application au contrôle ou à l'examen de tubes, de trous ou autres cavités.Technoscope for circular observation, consisting of an optical system with lenses or optical fibers provided with a fiber light conductor, which cylindrically surrounds the optical system. There is provided, in front of the distal end of the fiber light conductor 4, a cylindrical glass ring 9 surrounding the distal end of the optical system 1, 2, 3 and producing a diffuse scattering of the light, and in front from the distal end of the optical system, a reflector fixed by means of a mount 10 on the distal end of the optical system or of the light conductor, namely a conical prism whose top is directed towards the optical system, or else a spherical or cylindrical body 12 of glass, the distal surface of which comprises a conical or spherical recess 13, formed by grinding, serving as a reflector and arranged symmetrically with respect to the axis of the optical system. Application to the control or examination of tubes, holes or other cavities.
