Thin aluminum/polyimide optical blocking filter study for the Lynx x-ray mission

Published

Author(s)

Benjamin Zeiger, Charles Tarrio

Abstract

The Lynx x-ray mission will push thin film filters to larger apertures and thinner profiles than those of any preceding mission. We present a study of the uniformity of deposition with existing technology and the consequences of oxidation on 10-15 nm Al films on LUXFilm polyimide. We present visible and infrared transmission measurements of thin aluminum filters and the results of a photon-driven oxidation study at the Beamline 1 of the Synchrotron Ultraviolet Radiation Facility. We conclude that, from a deposition and oxidation standpoint, Al optical blocking layers at this thickness are viable.
