Abstract: A fly-cutting system is disclosed, and in particular one that comprises a dynamically-controllable actuator for controlling the position, orientation, or both position and orientation of a cutting element carried by a fly-cutting head. In certain embodiments, the actuator can adjust the position or orientation of a cutting element, or both, hundreds or thousands of times per second, enabling precise control over the shape of features formed by the cutting element in a surface of a workpiece.

Abstract: A light directing film includes a structured major surface with a plurality of microstructures extending along a first direction. Each microstructure has a first region and a second region different from the first region, a substantially constant height in the first region and a non-constant maximum height in the second region greater than the substantially constant height in the first region, and a same lateral cross sectional shape in the first region and the second region.

Abstract: Optical films having anti-Moiré and anti-wetout features are described, along with systems and methods for making these optical films. A master used to make optical films is formed using a single axis actuator cutting along a trajectory that is out of plane with the surface of the master. Movement of the cutting tool along the trajectory cuts grooves having variable depth and variable pitch into the surface. Prisms formed from the master have variable depth, variable height prisms that provide anti-wetout and anti-Moiré features.
