Properties of beam splitters for a far ir Michelson interferometer have been calculated for four plastic materials: Surlyn, Aclar, Mylar, and Kapton. Although the materials are birefringent, the averaged optical constants are used; and it is shown that this procedure yields valid beam splitter characteristics.
