ABSTRACT:
The present disclosure is directed to optical devices including a light source and an optical film having a first surface disposed to receive light from the light source and a second surface facing away from the light source. The second surface includes a two-dimensional array of closely packed substantially hemispherically-shaped structures. In some implementations of the present disclosure, the optical film further includes a substrate portion having an optical characteristic different from optical characteristics of the second surface comprising the two dimensional array.
