Abstract: An optical stack includes a substrate, a radio-wave anti-reflection sheet configured to reduce reflection from the optical stack of radio waves at a predetermined operating frequency, and a visible light reflective, infrared light transmissive multilayer optical film disposed between the radio-wave anti-reflection sheet and the substrate. For radiation substantially normally incident on the radio-wave anti-reflection sheet and for a first frequency range at least 20 GHz wide, centered on the predetermined operating frequency, and disposed between about 1 GHz and about 120 GHz, a return loss of the optical stack is asymmetric about the predetermined operating frequency in the first frequency range. The optical stack has a largest return loss S11L in the first frequency range of less than −10 dB and a difference between the largest return loss S11L and a smallest return loss S11S in the first frequency range is less than about 2 dB.

Abstract: An optical construction includes an optical film between first and second prismatic films, which each include pluralities of parallel, linear first and second prisms. Each of the first and second prisms have opposing first and second sides extending from first and second ends of a base of the prism and meeting at a peak. The first and second sides make first and second base angles with the base of the prism. The peaks of the prismatic films face away from each other and the optical film. For a collimated, normally incident light, for at least a first wavelength in a first wavelength range, and for each of first and second polarization states: the optical film has an optical transmission of less than about 1%, and the optical construction transmits at least 1% of the incident light at an oblique angle greater than 5 degrees with respect to the optical film.
