Abstract
Polymeric multilayer optical films are described. More particularly, polymeric multilayer optical films having a first optical packet and a second optical packet are described. The second optical packet is disposed on the first optical packet. How the configuration of the layers of the optical packets affect hemispheric reflectivity of the overall film is also described. The polymeric multilayer optical film reflects more than 95% of light from 400 nm to 700 nm at normal incidence.
