Why Alluxa - Alluxa is an ISO 9001:2015 certified, ITAR registered manufacturer of high-performance optical filters and thin-film coatings. Alluxa has rapidly grown from a small startup to a world leader in precision thin films. Our engineering team has been instrumental in achieving this growth by refining our advanced SIRRUS Plasma Deposition process, designing and building our coating equipment, and dedicating a large amount of resources to research and development. Meanwhile, our leadership team has been reinvesting in the business and creating a progressive company culture that benefits both our customers and our people. Located in Santa Rosa, CA, Alluxa was founded in 2007 by a team of thin film deposition veterans. Alluxa's core team brings together decades of expertise and diverse backgrounds in deposition, automation, metrology, and optics. Alluxa produces its filters with a new class of custom optical thin film coating equipment designed and built by our team. The combination of our state of the art automation, proprietary control algorithms, and a patented plasma thin film deposition process allows the world's most difficult filters to be created in a fraction of the time required by other hard coating methods. Using this proprietary thin film optical coating platform, Alluxa is delivering custom solutions to the most challenging optical coating problems - including bringing lower costs to high performance requirements.
