ABSTRACT:
The method of selecting a light redirecting film or optical panel includes the steps of providing a length of film or substrate having a pattern of optical elements that varies, then selecting an area of the film or substrate that has a pattern of the optical elements that best suits a particular application, and removing the selected area from the film or substrate to provide the light redirecting film or optical panel. The pattern may be a repeating pattern that varies at different locations on the film or substrate and may comprise a roll of the film or substrate from which the selected area(s) is removed.
