An optical film includes optical repeat units (ORUs) co-extruded and co-stretched with one another and numbering at least 10 in total. Each ORU has an average thickness of less than about 1500 nm and includes at least a polymeric A layer and a different polymer B layer. When adjacent data points in a scatter plot of thicknesses versus the numbers of the ORUs are connected with straight line segments to form a continuous line plot, the continuous line plot has a plurality of first lines where the ORU thickness in all of the first lines increases with a same one of increasing and decreasing ORU number, alternating with, and intersecting, a plurality of second lines where the ORU thickness in all of the second lines decreases with the same one of increasing and decreasing ORU number. The intersection points form at least three peaks alternating with at least two valleys.
An optical film comprising a plurality of optical repeat units (ORUs) co-extruded and co-stretched with one another and numbering at least 10 in total, each of the ORUs having an average thickness of less than about 1500 nm and comprising at least a polymeric A layer and a different polymer B layer, the ORUs sequentially numbered from a same first major side of the optical film to an opposite second major side of the optical film,
An optical film comprising a plurality of optical repeat units (ORUs) co-extruded and co-stretched with one another and numbering at least 10 in total, each of the ORUs having a peak reflectivity at a corresponding resonant wavelength (RW) and comprising at least a polymeric A layer and a different polymer B layer,
