WZW-Optic

What WZW-Optic does

WZW-Optic (legal entity: WZW OPTIC AG) is a privately held Swiss manufacturer of high-precision optical components and sub-systems, headquartered in Balgach, Switzerland. Founded in 1965 by Willi Weder Senior and now in its third generation of family ownership, the company operates from a 3,000 m² production facility and serves 200+ customers across 50+ industries in 30+ countries, with approximately 90% of revenue from international exports. Its primary customer verticals are semiconductor lithography and wafer inspection, defense and aerospace, laser and photonics, medical technology, metrology, and research institutions.

The company's technical differentiation is built on three proprietary manufacturing platforms. First, Plasma Jet Machining enables freeform optics, aspheres, and acylindrical lenses in fused silica with sub-30 nm RMSi surface accuracy and no subsurface damage. Second, Ion Beam Sputtering (IBS) coating achieves reflectivity above 99.999% with a Load-Lock system for AR, shortpass, longpass, and bandpass coatings, supported by two IBS coating systems installed in 2020. Third, Super Polishing delivers Sub-Ångström surface roughness (<0.6 Å rms), positioning the firm as Europe's leading commercial manufacturer of superpolished surfaces for ring laser gyroscopes, resonator blocks, and high-finesse cavities. These capabilities are validated by ISO 9001:2015, ISO Class 5 cleanroom, and Swiss Made certifications, and supported by an in-house metrology park including Zygo interferometry, Cavity Ring-Down measurement, and Hexagon 3D multisensor systems.

WZW-Optic operates a direct, sales-led B2B go-to-market with quote-driven, project-based pricing for custom optics, assemblies, coating services, and engineering (ZEMAX/OpticStudio, Onshape, FTG Filmstar). Customers engage through the company website, direct email ([email protected]), and phone for technical consultation from prototype through series production, with multi-year contract cadences and an average customer relationship of 15+ years. Leadership transitioned in 2022 to Samuel Zuberbühler (Board Chairman), Yener Agdag (Managing Director), and more recently Claudio Meli (CEO and CFO), while operational focus remains on advancing precision optics into semiconductor, defense, and emerging quantum/photonic applications.
