Title:
GRADED PLASTIC OPTICAL ELEMENT AND METHOD FOR PRODUCING THEREOF
Document Type and Number:
WIPO Patent Application WO2001043954
Kind Code:
A9
Abstract:
The present invention provides a method for forming a transparent optical element, such as an optical fiber, having a graded index of refraction. One preferred practice of the invention employs a hollow tube formed of an amorphous fluoropolymer and fills the tube with a liquid dopant material having an index of refraction that is different than that of the fluoropolymer. The heating of the filled tube for a sufficient duration causes the diffusion of the dopant material through the fluoropolymer, thereby producing a graded distribution of the dopant and hence a graded refractive index.
