Abstract
Official abstract text for this publication.
A broadband partial reflector includes a multilayer polymeric optical film having a total number of optical repeating units that monotonically increases in thickness value from a first side to a second side of the multilayer polymeric optical film. A baseline optical repeating unit thickness profile is defined by a first plurality of optical repeating units and having a first average slope, and a first apodized thickness profile of the multilayer polymeric optical film is defined by a second plurality of optical repeating units having a second average slope being at least 5 times greater than the first average slope. The second plurality of optical repeating units define the first side of the multilayer polymeric optical film and join the first plurality of optical repeating units. The second plurality of optical repeating units are in a range from 3-15% of the total number of optical repeating units.
