APPARATUS FOR THE MANUFACTURE OF DIELECTRIC MULTIPLE LAYERS (EINE APPARATUR ZUR HERSTELLUNG DIELEKTRISCHER VIELFACHSCHICHTEN),
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)
