Journal ArticleDOI
Design and fabrication of stress-compensated optical coatings: Fabry-Perot filters for astronomical applications.
TL;DR: An optimization tool for the design of optical filters taking into account both the optical and mechanical properties of the substrate and of the individual deposited layers is proposed.
Journal ArticleDOI
Adhesion improvement of plasma-deposited silica thin films on stainless steel substrate studied by x-ray photoemission spectroscopy and in situ infrared ellipsometry
N. Bertrand,Bernard Drevillon,A. Gheorghiu,C. Senemaud,Ludvik Martinu,Jolanta-Ewa Klemberg-Sapieha +5 more
TL;DR: In this paper, an x-ray photo-emission spectroscopy (XPS) and in situ IR ellipsometry performed on very thin films (≈30 A) was performed on stainless steel, and the removal of adsorbed hydrocarbons on the metallic surface by all plasma treatments.
Journal ArticleDOI
Tribological properties of duplex treated TiN/TiCN coatings on plasma nitrided PH15-5 steel
I. Zukerman,A. Raveh,Y. Landau,R. Weiss,Roni Z. Shneck,Y. Shneor,Haim Kalman,J.E. Klemberg-Saphieha,Ludvik Martinu +8 more
TL;DR: In this article, the thickness of the compound layer fabricated by a single mode plasma is ∼ 5μm, while that fabricated by dual-frequency mode plasma was ∼ 35μm.
Journal ArticleDOI
Growth and properties of high index Ta2O5 optical coatings prepared by HiPIMS and other methods
M. Hála,Richard Vernhes,Oleg Zabeida,Etienne Bousser,Jolanta-Ewa Klemberg-Sapieha,R. Sargent,Ludvik Martinu +6 more
TL;DR: In this article, the effect of specific deposition conditions on the growth characteristics, surface morphology, as well as on the optical and mechanical properties of amorphous Ta 2 O 5 films was investigated.
Journal ArticleDOI
Active metameric security devices using an electrochromic material.
TL;DR: A design methodology for metameric filters based on the luminous efficiency curve of the human eye results in filters with a lower number of layers and hence lower fabrication costs, and with a higher color difference sensitivity under various illuminants and for nonstandard observers.
