Abstract: An optical construction includes an optical film including a plurality of polymeric layers and an optical retarder disposed on the optical film. For a substantially normally incident light and for a visible wavelength range of about 420 nm to about 680 nm and an infrared wavelength range of about 900 nm to about 1100 nm: for the incident light polarized along each of mutually orthogonal in-plane first and second directions. the plurality of polymeric layers has an optical transmittance of greater than about 60% for at least one visible wavelength in the visible wavelength range and an optical reflectance of greater than about 60% for at least one infrared wavelength in the infrared wavelength range. For the incident light polarized along at least one of the first and second directions, the optical retarder has an optical retardance of greater than about 1000 nm at the at least one visible wavelength.
