Abstract
Inhibiting formation of optical artifacts in a multi-layer film polarizer of an optical imaging assembly that includes a polarizing beam splitter. The beam splitter may include a multilayer reflective polarizing film having at least two materials, one of which may exhibit birefringence after uniaxial orientation; an adhesive disposed on the multilayer reflective polarizing film; and at least a first prism disposed on the adhesive. The adhesive may include a plasticizer for inhibiting formation of optical artifacts in the polarizing film.
