An angular selective film is configured to have a higher transmittance for radiation having an incidence angle in a specified range as compared to radiation having an incidence angle outside of the specified range, and includes a plurality of multilayer modules stacked substantially along a normal direction of the angular selective film. Each multilayer module includes at least first and second polymer layers, which have at least one of the following properties: (i) the first polymer layer is isotropic, the second polymer layer is anisotropic, the refractive indices of the first and second polymer layers are substantially the same in a first direction, and are different in a second direction, or (ii) both the first and second polymer layers are anisotropic, the refractive indices of the first and second layers are substantially the same in a first direction, and are different in the second direction.
