Abstract

A polymeric infrared window (10) is described which comprises a sheet of polymeric material (14). Sheet 14 further may comprise a layer of molecular weave polymer material (34) fixed to a electromagnetic interference shield (32). In addition, a polymeric sheet (42) may be embossed with a binary defractive pattern (40) to create a polymeric defractive lens (38).
