Abstract

The optical properties of aluminum and aluminum: magnesium fluoride semitransparent coatings for multiple-beam interferometry in the ultraviolet (>1800 Å) have been measured. There is good agreement between experimental values of reflectance and transmittance and those computed on the basis of extrapolated optical constants of aluminum. The effects of evaporation conditions, including rate of evaporation and the content and pressure of the residual atmosphere, on optical properties are discussed and the performance of these coatings for interferometry is summarized.
