About Sirrus Technology

Alluxa, founded in 2007, operates as a manufacturer of specialized optical filters and thin-film coatings. The company is headquartered in Santa Rosa, California, and was established by a team of veterans in the thin-film deposition industry, including founder Mike Scobey, who also served as CEO and CTO. This team's collective experience in deposition, automation, metrology, and optics has been central to the company's trajectory. Peter Egerton has been with the company since 2009 in various executive roles and was part of the Technical Advisory Board from 2007. In September 2020, EnPro Industries announced its acquisition of Alluxa for $255 million, a transaction that was completed in October 2020.

The company's business model centers on providing custom, complex, precision coating solutions to a diversified customer base across the industrial technology, life sciences, and semiconductor markets. Alluxa collaborates directly with clients to develop products for challenging applications, serving customers across the Americas, Europe, and Asia. Revenue is generated through the sale of these specialized optical filters and coatings. The business serves a wide array of sectors, including aerospace, biotechnology, telecommunications, remote sensing, and medical instrumentation.

A core component of Alluxa's operations is its proprietary SIRRUS™ plasma deposition platform. This technology, developed in-house, enables the production of hard-coated optical filters with high-performance characteristics. The platform's automation and control algorithms allow for the rapid creation of difficult-to-manufacture filters. Products include the ULTRA Series of optical filters, which feature bandpass, multiband, dichroic, edge, and notch filters for wavelengths from the UV to the IR spectrum. These filters are designed for integration into sophisticated instruments used for applications like LIDAR, fluorescence microscopy, and DNA sequencing. The SIRRUS technology allows for the creation of coatings with features like steep edges, high transmission, and deep blocking, which are critical for advanced optical systems.
