Abstract

There is disclosed an improved integral optical device of the type produced by creating optical patterns in porous glass bodies, especially patterns involving gradient refractive index distributions. The optical strength of an element, such as a lens, in such an optical pattern is increased by treatment with a polymerizable, organo functional silicone fluid while the matrix glass is sealed.
