Title (EN) GLASS COMPOSITION ADAPTED FOR MAKING PLANAR OPTICAL ELEMENTS
(FR) COMPOSITION DE VERRE ADAPTÉE A LA RÉALISATION D'ÉLÉMENTS OPTIQUES PLANS
Abstract:
(EN) The invention relates to glass compositions adapted for making planar optical elements particularly intended for making imaging devices. The planar optical elements are made of a glass having a low thermal expansion coefficient and include an ionic pattern that is formed by an alkaline ion exchange processing of the glass with silver ions and exhibits a high refraction index variation. The invention also relates to a method for making said planar optical elements.
(FR) La présente invention concerne des compositions de verre adaptées à la fabrication d'éléments optiques plans destinés notamment à la réalisation de dispositifs d'imagerie. Les éléments optiques plans sont constitués d'un verre ayant un faible coefficient d'expansion thermique et ils comprennent un motif ionique formé par un traitement d'échange des ions alcalins du verre par des ions argent qui présente une variation d'indice de réfraction élevée. L'invention concerne également le procédé de fabrication desdits éléments optiques plans.
