Abstract
An integral optical stack including a structured optical film having alternating first and second segments including plurality of polymeric layers. Each pair of first and second segments define an inclusion angle of between about 50 degrees and about 110 degrees therebetween. Planarizing films are disposed on opposite first and second sides of the structured optical film. Each of the first and second sides has an average peak-to-valley nonlinearity. The planarizing films reduce the average peak-to-valley nonlinearity of the corresponding side of the structured optical film by at least a factor of 2. For each incident angle of between about zero and 30 degrees, the plurality of polymeric layers in each of the first and second segments has an average optical transmittance of greater than about 70% in a visible wavelength range and an optical reflectance of greater than about 60% for at least one wavelength in an infrared wavelength range.
