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.

Method of assembling optical systems and minimizing retardance distortions in optical assemblies

A polarization switching apparatus has a first birefringent polarizer formed as a composite prism and disposed to direct incident light of a first polarization along a first optical path and light of a second polarization along a second optical path, wherein the second optical path is oblique to the first optical path. A beam redirector is disposed to redirect the first optical path from the first birefringent polarizer toward an input face of a second birefringent polarizer; wherein the second birefringent polarizer is also formed as a composite prism and is disposed to combine incident light of the first and second polarizations onto a common output path. A shutter apparatus is actuable to selectively block light of the first polarization or light of the second polarization from the input face of the second birefringent polarizer.
