... Optical characteristics of amorphous SiO 2 in the region 1400-200 cm -1 . ... Optical constants: . amorphous SiO 2 Some details: . Reflectance of polarized radiation at the incidence angle 12 deg was measured in the range from 1400 to 200 cm -1 for several samples of amorphous SiO 2 . Special technique applied allowed to reduce the relative errors downto 1% for the reflectance values of 0.005-0.8. The optical constants were obtained by the Kramers-Kronig method. ...
