Abstract
The production and the performance of dielectric multilayer mirrors for Fabry-Perot interferometers from 20000 Å to 2350 Å are described. Details of the evaporation apparatus and techniques are given. The optical data — reflection factor, absorption factor and flatness — are represented graphically and discussed. For all wavelength cryolite served as low refractive material. The high refractive materials used were ZnS for wavelengths from the infrared to λ>4100 Å, Sb2O3 for λ between 4200 Å and 3200 Å and PbF2 for the shorter wavelengths to λ=2350 Å. For PbF2 an exciton-band at 2190 Å has been found.
