Abstract:
A consolidated multilayered GRIN optical material includes a multilayered composite GRIN sheet that includes a plurality of consolidated coextruded multilayered polymer films. Each of the multilayered polymer films includes a plurality of at least two alternating layers (A) and (B). Layer (A) includes a first blend of polymer components and layer (B) includes a second blend of polymer components. The multilayered composite GRIN sheet has an external optical transmission of at least 80% at a wavelength of 633 nm measured using UV-VIS spectroscopy and is free of intralayer polymer domains at least 1 micron size scale in any dimension.
