Research abstract
Performance of present and planned space-borne remote sensing instruments could be significantly improved by the incorporation of thermally stable optical coatings. We propose to investigate the use of ion-assisted deposition (IAD) in the fabrication of large area narrowband interference filters which are uniform to within 2 Angstroms. Issues such as effect of the ion beam on uniformity, in situ measurement of uniformity, and control of the key parameters will be addressed.
