Abstract
According to some embodiments a method of assembling an optical system comprises steps of: measuring retardance profiles of a plurality of optical elements, relatively positioning the optical elements in relative orientations that enhance complementarity between the retardance profiles of the optical elements, and securing the combinations of relatively oriented optical elements together, to control or minimize the combined retardance of the stacked optical elements.
