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.

Abstract: The method of aligning a cylindrical lens in a lens assembly includes attaching the cylindrical lens to a lens fixture and interfacing the lens fixture to a support structure in which the cylindrical lens can be placed in a frontwards and backwards orientation. The method also includes capturing respective first and second line images of respective first and second focus lines as formed by the cylindrical lens in the forwards and backwards orientations. The method further includes establishing a relative orientation of the first and second line images and using the established relative orientation to determine an amount of angular misalignment of the cylindrical lens relative to a reference direction provided by the support structure. The method can include rotating the cylindrical lens relative to the lens fixture to reduce the amount of angular misalignment to be within an angular alignment tolerance.
