What Alluxa does

Alluxa is a U.S.-based manufacturer of high-performance optical filters and thin-film coatings, headquartered in Santa Rosa, California, and operating since 2007 as a wholly-owned subsidiary of Enpro Industries (NYSE: NPO). The company's core technology is its proprietary SIRRUS Plasma Deposition process, a hard-coated thin-film interference filter manufacturing method that the company claims delivers superior wavelength precision, durability, and production speed relative to traditional coating techniques. Supporting the manufacturing platform is the proprietary HELIX Spectral Analysis System, which the company states can resolve sub-0.1nm bandwidths and measure blocking to OD9, enabling in-house verification of ultra-high-performance filters that standard spectrophotometers cannot characterize.

The ULTRA Series product line spans ultra-narrow bandpass filters, single and multi-bandpass filters, notch filters, dichroic filters, dielectric mirrors, fluorescence filter sets, and soft-coating replacement filters. Alluxa also offers custom and OEM filter development services for specialized applications. End-markets include LIDAR systems (autonomous vehicles, atmospheric and satellite altimetry), life sciences and diagnostics (qPCR, fluorescence microscopy, flow cytometry), aerospace and defense (NASA ICESat-2 ATLAS, Mars Perseverance Rover fluorescence spectrometer), and astronomy (Texas A&M ETSI instrument). The company holds ISO 9001:2015 certification and ITAR registration, supporting defense and government procurement eligibility.

Revenue is generated through direct B2B sales of catalog and custom optical filters on a quote-based, project-driven basis, with EXW pricing from the factory and net-30 payment terms for approved customers. GTM is sales-led and engineering-driven, supported by technical content marketing (white papers, learning center, webinars), industry conference presence (e.g., SPIE Defense & Security), and a website-based quote request system for custom and OEM filter development. Alluxa serves a global customer base across scientific instrumentation, defense, aerospace, and life sciences markets.
