Lumics

What Lumics does

Lumics GmbH is a Berlin-based manufacturer of high-performance semiconductor diode laser components and subsystems, founded in 2000 by three German physicists. The company operates a vertically integrated production model spanning the full value chain from wafer processing to fiber-coupled laser modules, anchored by in-house chip fabrication in ISO 5 and ISO 4 cleanrooms at a purpose-built 50,000 sqm Berlin campus occupied since 2016. Lumics produces diode lasers across three semiconductor material platforms — GaAs/AlGaAs, InP, and GaSb — covering wavelengths from 670nm to 1940nm and power outputs from milliwatts (singlemode) to over 800W (multimode). Core product lines include singlemode BTF14 14-pin butterfly lasers, multimode TO220 2-pin lasers, the LuOcean multi-emitter module series (Mini4, Mini8, P2, M4), and complementary OEM driver kits, chiller units, and fiber patchcords. The proprietary facet passivation process, patented and certified to quasi-Telcordia standards, is the company's central technical differentiator, enabling high power density without catastrophic optical mirror damage.

The company's commercial focus spans seven application verticals: medical and healthcare (the primary segment), agriculture, sensing and security, communication and telecom, industrial material processing, seeding and pumping, and life science research. Use cases range across surgical and therapeutic medical devices, laser-based weed control, LiDAR and distributed temperature sensing, free-space optical communication, industrial soldering and plastic welding, and pumping/seeding for fiber and solid-state lasers. Revenue is generated through direct enterprise sales supported by regional key account managers covering Germany, UK, France, Czech Republic, Korea, China, and the US, complemented by authorized distribution partners Connet Fiber Optics (China) and Opto Science (Japan). Pricing is quote-based for OEM customers with no public price disclosure; volume is sold as discrete hardware components and subsystems, not under subscription or licensing models.

Lumics has been affiliated with Berlin.Industrial.Group (B.I.G.), a coalition of specialized technology companies, since 2012, gaining access to shared corporate services (HR, data protection, sustainability) while maintaining operational independence. The company holds DIN EN ISO 9001 certification since 2006, with RoHS and REACH compliance, and operates as Lumics GmbH under Berlin jurisdiction (HRB 77356). Headcount is reported in the 11-50 range; revenue is not publicly disclosed, no venture or private equity funding has been reported since a December 2005 round, and the company does not disclose detailed ownership percentages.
