Axsun Technologies

What Axsun Technologies does

Axsun Technologies is a designer and manufacturer of miniaturized optical micro-instruments, with its core specialty in Swept-Source Optical Coherence Tomography (SS-OCT) laser systems used for high-speed, high-resolution imaging in medical and industrial applications. Founded in 1998 and historically based in Billerica, Massachusetts, Axsun was acquired by Excelitas Technologies Corp. and has been fully integrated as a retained brand within Excelitas's broader photonic technology portfolio; the www.axsun.com domain now redirects to www.excelitas.com, and Axsun SS-OCT Laser customer support is delivered through Excelitas's service portal. The acquisition positioned Axsun's SS-OCT laser technology alongside Excelitas's wider offering of cameras (PCO-brand scientific and high-speed cameras), illumination (X-Cite fluorescence illuminators, Cermax xenon lamps, Noblelight IR/UV sources, LED systems), optics (LINOS standard elements, custom optical assemblies), UV curing systems (OmniCure, Phoseon VeriCure), thermal infrared sensors, photonic detectors, and night vision goggle modules.

Axsun/Excelitas generates revenue through hardware sales of photonic products and components, complemented by professional-services revenue from custom OEM solution design and manufacturing. The company sells to OEMs and end-users in Medical and Life Sciences, Advanced Industrial Manufacturing, Aerospace and Defense, Next-generation Semiconductor, Automotive, Consumer Products, and Sciences, with primary commercial emphasis on the first four verticals. Pricing is quote-based B2B with multi-year contracts, distributed through a combination of direct enterprise field sales for custom solutions, a global distributor network for standard products, and OEM partnerships for embedded optical sub-systems. ITAR compliance supports defense and night vision business, and dedicated customer support portals serve each major product line. The company is privately held, with no public revenue or ownership structure disclosed.
