CA 2293243

Polymeric optical articles, including gradient index optical preforms and fiber produced therefrom, are described. Methods for producing the optical articles using platicizers and/or dopants in the sheathing of the articles are also described. Gradient index optical articles made according to the invention have excellent optical characteristics, enhanced mechanical properties and environmental stability, and enable more flexibility in the selection of materials.

L'invention concerne des articles d'optique polymères, comprenant des préformes et des fibres optiques à gradient d'indice produites à partir de ceux-ci. Des procédés de production des articles d'optique utilisant des plastifiants et/ou des dopants dans le revêtement de ces articles sont également décrits. Des articles d'optique à gradient d'indice fabriqués selon l'invention présentent d'excellentes caractéristiques optiques, des propriétés mécaniques et une stabilité à l'environnement améliorées, et offrent plus de flexibilité dans la sélection des matières.
