In early January 2007, Helia will take delivery and install a new multilayer coating system based on DC pulsed sputtering.  The new sputtering system will provide a range of dense, low-stress films which can be used in a range of highly complex multilayer filter structures, including rugates.  The coating system will complement Helia existing ion-assisted deposition systems and is part of the company's commitment to investment in state-of-the-art coating technology.  For more information, please contact info@helia-photonics.com
