About Eule27
Eule27 AG is a Swiss software provider for optical thin-film coating based in Zug. The company develops EulenStudio, a software for the design and modeling of optical interference coatings as well as for real-time reverse engineering, optical in-situ and ex-situ monitoring, and closed-loop control in coating systems. The modules adapt layer thicknesses and optical constants (n, k) from interference spectra, calculate tolerance and yield before the batch, and close the control loop between the spectrometer and the coater. EulenControl is already in production; the staged release of EulenStudio is planned for October 2026. Alongside its software, Eule27 acts as an engineering partner: simulation models, data analysis, AI production optimization, metrology consulting and machine interfaces for coating system manufacturers. Target industries are precision optics, interference filters, large-area coating of architectural and solar glass, antireflective coating as well as optical and decorative components.

Quality
The models are validated against real production data; accuracy is robustly verified rather than relying solely on error metrics such as MSE. Reference project: integrated dual-detector measurement system with measurement procedures and thin-film simulation models for AR coating on textured solar glass.
