A reflective polarizer includes a plurality of first layers disposed on a plurality of polymeric second layers. Each of at least 30% of the first layers includes at least 30% by weight of an inorganic material. For an incident light incident in a plane and a first incident angle, the reflective polarizer and the first layers have respective average optical reflectances R3v and R1v in a visible wavelength range and respective average optical reflectances R3ir and R1ir in an infrared wavelength range, R1v<R3v and (R1ir−R3ir)>10%, when the incident light is polarized along a first direction; and for the visible wavelength range and for a second incident angle, the plurality of polymeric second layers has an average optical reflectance R2v(x) when the plane includes the first direction and an average optical reflectance R2v(y) when the plane includes a second direction, 5% <R2v(y)<R2v(x)<60%.
An integral optical construction comprising a mesh disposed on an optical film comprising a plurality of polymeric first layers numbering M1 in total, M1≥10, the mesh comprising a plurality of traces connected to define a plurality of enclosed open areas therebetween, wherein each of the traces comprises a plurality of alternating electrically conductive second and electrically insulative third layers numbering M2 in total, 4≤M2<M1, each of the first through third layers having an average thickness of less than about 500 nm, wherein the mesh is electrically conductive along at least one direction across the integral optical construction.
A method of making an integral optical construction, the method comprising:
