Abstract

L'invention concerne une optique hybride avec un élément optique en verre et une monture en matière plastique, au moins un segment d'appui de l'élément en verre reposant sur la monture. Dans un premier exemple de réalisation de l'invention, la monture est faite dans l'une des matières plastiques résistantes suivantes : ETFE, ECTFE, PCTFE, PA, PPO, PE, PMMA, PP, PS, PES, PTFE, PFA, PVC ou PMP. Dans un deuxième exemple de réalisation de l'invention, l'élément en verre est fait en verre de quartz ou en verre de phosphate ou en verre non alcalin ou bien possède une couche barrière s'opposant à la diffusion de métaux alcalins ou alcalino-terreux. Grâce à de tels éléments en verre, on obtient une moindre diffusion des métaux alcalins ou alcalino-terreux. Dans le procédé selon l'invention d'augmentation de la durabilité d'une optique hybride comprenant un élément en verre et une monture en matière plastique, au moins un segment d'appui de l'élément en verre reposant sur la monture, l'élément en verre est formé à chaud sous une atmosphère contenant de l'oxygène, ou bien des métaux alcalins ou alcalino-terreux sont éliminés au moins au niveau des segments d'appui de l'élément en verre avant un surmoulage de l'élément en verre par la matière plastique de la monture. Grâce à de tels éléments en verre, on obtient une moindre diffusion des métaux alcalins ou alcalino-terreux, si bien que la matière plastique de la monture est moins sollicitée. Dans les deux variantes de l'optique hybride selon l'invention et dans le procédé de fabrication selon l'invention d'optique hybrides, on évite un affaiblissement de la matière plastique de la monture, si bien que l'optique hybride selon l'invention présente une meilleure durabilité et une meilleure résistance.
