Method of selecting a light redirecting film
First Claim
1. A method of selecting a light redirecting film for a particular application comprising the steps of providing a length of film having a pattern of optical elements on or in the film that varies, selecting an area of the pattern that best suits a particular application, and removing the selected area from the film to provide the light redirecting film, the selected area having substantially less than a 100% of the total area of the pattern.

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.

- 10. A method of selecting a light redirecting film for a particular application comprising the steps of providing a length of film having a pattern of individual optical elements of well defined shape on or in the film that varies, the optical elements being quite small in relation to a width and length of the film, selecting an area of the film that has a pattern of the optical elements that best suits a particular application, and removing the selected area from the film to provide the light redirecting film, the selected area having substantially less than a 100% of the total area of the pattern.
