Abstract : An apparatus for the manufacture of dielectric multiple layers is described. The optical thickness of the layer is measured during the evaporation process using light of a given wavelength by determining the reflectivity with a two-ray chopped-light process. With this method, the determination of layer thickness is largely independent of external disturbances. A Fabry-Perot interferometer was manufactured with these dielectric multiple layers and the hyperfine structure of the Hg e line 4358 A from a low-pressure mercury burner was photographed. (Author)
