Achromatic and super-achromatic zero-order waveplates

Abstract

The waveplates are widely used to transform a state of polarization radiation. This paper describes anisotropic properties of polymethylmethacrylate (PMMA) subjected to one-axis stretching and a construction and properties of achromatic and super-achromatic waveplates produced of PMMA. The most technological method to produce such waveplates is the controlled stretching of PMMA sheets to a retardation needed. This method excludes the mechanical treatment of waveplates. In generality of properties, these waveplates are ones of the best and unique in their dimensions, which may be up to 60 mm.
