PACA2m magnetron sputtering silver coating: a solution for very big mirror dimensions

Today high angular resolutiontelescopes for space observation satellites require primary mirrorswith larger and larger dimensions. For such mirrors, high-performance silver coating is required and is a key part of the component. For more than 20 years, CILAS has developed an expertise in the field of thin film opticalcoatings in order to answer a wide range of spectral performances and produce high quality thin film coatings. Among the various coating technologies that may answer such demand, magnetron sputtering is particularly well-suited to produce dense layers with improved mechanical performances and a high level of uniformity.
