Description

LISA Pathfinder and LISA use stable optical benches with optics attached by silicate bonding to perform length measurements. The optical coatings defining the function and performance of the optical components such as mirror, beam splitter or polarizing beam splitter must withstand the conditions during launch and operation in space and deliver constant performance. This requires durable and stable optical coatings. This talk discusses coatings produced by Ion Beam Sputtering (IBS) and Magnetron Sputtering (MS) and highlights their properties and advantages compared to other coating techniques such as Electron Beam evaporation (EBE) or Ion Assisted Deposition (IAD). Examples of optical components produced for LISA experiments are discussed.
