Mastering tools and systems and methods for forming a cell on the mastering tools are provided. An exemplary method includes emitting a first laser light pulse from a laser for a first predetermined time interval such that at least a portion of the first laser light pulse forms the cell on the mastering tool. The cell has an opening size within a range of 10-100 micrometers and an aspect ratio less than or equal to 1.25.

Mastering tools and systems and methods for forming a cell on the mastering tools

Mastering tools and systems and methods for forming a plurality of cells on the mastering tools are provided. In particular, the systems vary the geometry of the cells or the placement of the cells, or both, for forming a textured surface on a mastering tool.

Systems for forming a plurality of cells on the mastering tools

A light diffusing film for a back light display is described. The light diffusing film includes a unitary film consisting essentially of polycarbonate and a uniformly dispersed anti-static material in an amount sufficient to impart anti-static properties to the film. The anti-static material may comprise a fluorinated phosphonium sulfonate. The film may additionally include at least one textured surface for the low scattering of light. Alternatively, the film may additionally include a uniformly dispersed acrylic bulk scattering additive of particles having a mean particle size of from about 3 to about 10 microns and present in an amount from about 2 to about 7 percent by weight percent for the high scattering of light.

An embodiment of a method of making an optical film comprises heating the optical film comprising greater than or equal to 80 wt. % polycarbonate to a sufficient temperature to stretch the optical film, wherein the weight percent is based on a total weight of the optical film; and stretching the optical film. A resulting stretched optical film has a linear CTE measured in a direction parallel to a stretching direction of less than or equal to 50&#xd7;10cm/cm/&#xb0; C.

Methods of making and using optical film, light-diffusing film

A light collimating and diffusing film and a method for making the film are provided. The film includes a plastic layer having a first side and a second side opposite the first side and at least a first peripheral edge. The first side has a first textured surface, wherein between 7 to 20 percent of slope angles on the first textured surface proximate a first axis has a value between zero and five degrees. The first axis is substantially parallel to the first peripheral edge. The plastic layer collimates light propagating therethrough.
