Concept for Measuring and Evaluating Optical Anisotropy Effects in Tempered Architectural Glass

Steffen Dix, began his career at seele GmbH in 2003 as a technical draftsman apprentice. In 2015, he received a Master's degree in civil engineering with a focus on steel, lightweight, and glass construction from the University of Applied Sciences in Munich. During his studies from 2009 to 2015, he worked in the Labor für Stahl- und Leichtmetallbau, starting as a working student and later as a Research Assistant. His research focused on adhesives in façade design and the strength and quality of pre-stressed glass products, culminating in his dissertation on the measurement and evaluation of optical anisotropy effects in tempered architectural glass. From 2016 to 2022, he also worked as a freelance expert in glass and façade construction for the Ingenieurbüro für Bautechnik Schuler in Karlsruhe. Since 2022, the author is working as Technical Solution Manager at Josef Gartner GmbH (Permasteelisa), where he develops individual and innovative façade constructions.
