What Luxium Solutions does

Luxium Solutions is a US-based specialty materials manufacturer headquartered in Hiram, Ohio, producing high-performance crystals and optical components for radiation detection, photonics, semiconductor, aerospace/defense, and medical imaging applications. Its core product lines span scintillation crystals (NaIL, CLLB, enhanced LaBr3, CsI(Tl), LYSO, BGO) and integrated detector assemblies for alpha, beta, neutron, gamma-ray, and X-ray detection; synthetic sapphire and large-format sapphire tubes for semiconductor processing and harsh-environment industrial use; garnet substrates (GGG, SGGG, NGG) for epitaxial semiconductor crystal growth; and precision optics including X-ray analyzers, hollow retroreflectors, monolithic interferometers, and electronic autocollimators. The company holds over 170 patents, operates large-format crystal growth assets (up to 8-inch CsI(Tl) crystals and the world's largest single crystal sapphire tube), and differentiates through proprietary co-doping technologies that materially reduce afterglow and improve energy resolution.

Luxium was formed in 2022 when SK Capital Partners and Edgewater Capital Partners carved the crystals business out of Saint-Gobain, and expanded in 2024 via the acquisitions of PLX Inc. and Inrad Optics (the latter for approximately $19 million). In February 2026, the company was acquired by Excelitas Technologies (an AEA Investors portfolio company), creating a vertically integrated sensing, detection, and imaging platform. Luxium operates as a B2B sales-led enterprise with custom quote-based pricing, multi-year contracts, and direct engagement with OEMs and system integrators across government/security, medical imaging, semiconductor fabrication, aerospace/defense, and research/synchrotron end markets. The company is now a wholly-owned subsidiary of Excelitas Technologies Corp.
