Abstract
A computer-implemented method for optical element fabrication with optical scanner feedback includes initiating the optical scanner to obtain an optical measurement of an optical layer of a multi-layer film. A rotational orientation for an optical element that is to be cut from the multi-layer film is then determined based on the optical measurement. The method also includes initiating a cutting instrument to cut the optical element from the multi-layer film at the rotational orientation.
