More Information
Summary:An optically diffusive film includes an optical substrate layer with opposing first and second major surfaces; and an optical layer disposed on the second major surface of the optical substrate layer and including a structured major surface having a plurality of spaced apart elongated structures elongated along a same first direction and arranged at a substantially uniform density, each elongated structure including a peak such that, in a plane of a cross-section of the elongated structure that is parallel to the first direction and comprises the peak, the elongated structure has a substantially flat top region; wherein for substantially normally incident light and a visible wavelength range and an infrared wavelength range, the optical substrate layer has an average total transmittance or reflectance of greater than about 60% in the visible wavelength range and an average specular transmittance of greater than about 60% in the infrared wavelength range.
