Abstract

L'invention se rapporte au domaine des pièces et des composants optiques, et concerne un réflecteur. Le réflecteur comprend deux faces réfléchissantes (10, 20) agencées de manière à être en intersection. Les rayons de la lumière réfléchie par les faces réfléchissantes se propagent dans la même direction et sont parallèles les uns aux autres. Le faisceau de lumière réfléchi par les faces réfléchissantes agencées de manière à être en intersection possède une portée plus grande que celle d'un faisceau de lumière réfléchi par une seule surface réfléchissante. La portée du faisceau de lumière réfléchi par les faces réfléchissantes agencées de manière à être en intersection du réflecteur équivaut à deux fois la portée d'un faisceau de lumière réfléchi par une seule surface réfléchissante, ce qui augmente la portée de réflexion du faisceau et permet la mesure d'un matériau ayant un grand diamètre.
