摘要:
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.
