1. A method of manufacturing an optical film, comprising:
- providing a plurality of inorganic fibers as a continuous layer of fibers;
embedding the continuous layer of inorganic fibers within a polymer resin; and
solidifying the polymer resin to produce a composite layer of polymer and inorganic fibers, a refractive index of the polymer resin substantially matching a refractive index of the inorganic fibers.

Abstract
Optical bodies, for example optical films, are formed with inorganic fibers embedded within a polymer matrix. In some embodiments, the refractive indices of the inorganic fibers and the polymer matrix are matched. There need be no bonding agent between the fibers and the polymer matrix. The inorganic fibers may be glass fibers, ceramic fibers, or glass-ceramic fibers. A structure may be provided on the surface of the optical body, for example to provide optical power to light passing through the optical body. The body may be formed using a continuous process, with a continuous layer of the inorganic fibers being embedded within the matrix which is then solidified.
