Competition was limited to BEAM, because BEAM has invented a one of a kind instrument to producing custom diffractive waveplates with 6.4 micrometer square pixels over a working area of 12.3mm X 6.9mm. They use their own developmental materials that have shown diffraction efficiencies greater than 99%. They can tune their process to any operating wavelength. They have demonstrated high optical clarity.
