What ISTEQ does
ISTEQ B.V. is a privately held Dutch photonics equipment manufacturer headquartered at the High Tech Campus Eindhoven. Founded in 2013 with 11–50 employees, the company designs and produces plasma light sources spanning the X-ray to infrared spectral range, sold under two product families. The TEUS series (S-100, S-200, S-400) delivers Laser-Produced Plasma (LPP) EUV light at 13.5nm using a fast-rotating liquid-metal (tin) target with proprietary debris-mitigation, targeting semiconductor mask inspection (PMI, AIMS, MBI), wafer inspection, EUV optics chain inspection, and material science applications. The XWS series (XWS-30, XWS-65, XWS-X) consists of continuous-wave laser-plasma discharge broadband sources covering 190–2500nm with high spectral brightness (up to 140 mW/(mm²·nm·sr) on XWS-X) and electrodeless designs extending source lifetime to ~10,000 hours, serving spectroscopy, microscopy, metrology, chromatography detection, microfluidics, photodynamic therapy, and photopolymerisation.
The company's underlying technology rests on patented LPP architectures with worldwide patent coverage on XWS light source technology and debris-mitigation techniques. Performance positioning emphasizes spectral brightness (up to 500 W/mm²·sr on S-400), extreme temporal/spatial stability (STD as low as 0.05% on XWS-X), long collector lifetime (up to 18 months with special membrane filter), and 24/7 uptime suitable for production environments. A modelling and simulation service line offers multi-physics, multi-scale virtual product testing and optimization using high-performance computing as an adjacent capability.
ISTEQ monetizes almost exclusively through direct enterprise sales of high-mix, configurable capital equipment, supplemented by custom-design services for specific industrial requirements. Pricing is not publicly disclosed. Go-to-market is concentrated in three verticals: semiconductor industry (primary), material analysis and spectroscopy, and biomedical/analytical instrumentation. The company maintains a single headquarters location, has no disclosed funding rounds, no named customers in the source data, and no public M&A or partnership history. Customer success is signaled by technical specifications and lifetime metrics rather than by disclosed logos or volumes.

- MKS Instruments: MKS Instruments (via its Light & Motion / Spectra-Physics heritage) provides light sources, lasers, and photonics instruments for semiconductor and analytical markets — a broad incumbent with overlap to ISTEQ's EUV and broadband source offerings.
- ASML (Cymer): ASML, through Cymer, is the dominant supplier of EUV light sources integrated into its scanner platforms. While Cymer historically focuses on scanner EUV sources, ASML's overall position in EUV supply chain makes it the principal incumbent whose roadmap shapes the inspection-source opportunity ISTEQ targets.
Direct peers
- Excelitas Technologies: Excelitas manufactures broadband light sources, including plasma and arc-lamp sources, for analytical instrumentation, life sciences, and semiconductor inspection — a direct functional competitor to ISTEQ's XWS broadband plasma sources in spectroscopy and microscopy applications.
- Energetiq Technology: Energetiq (a Hamamatsu subsidiary) makes laser-driven light sources (LDLS) for semiconductor inspection, spectroscopy, and analytical instrumentation — a direct functional competitor to ISTEQ's XWS broadband plasma sources and a benchmark in EUV-adjacent applications.
