The International Symposium on Non-Oxide and New Optical Glasses (ISNOG) has become a pivotal event in the field of glass science and technology. With the rapid emergence of new types of non-oxide glasses and the discovery of their unique functionalities, the scope of ISNOG has broadened significantly. While originally centered on non-oxide glasses and their optical properties, the symposium now reflects major advancements across a range of glass systems and their novel physical behaviors. ISNOG serves as a key platform for academic exchange, technological innovation, and international collaboration within the global glass research community.
Held biennially since its inception in 1981 in Cambridge, UK, ISNOG has been hosted in numerous countries, including the USA, France, Japan, Australia, Germany, Brazil, the Czech Republic, India, China, Korea, Russia, and Canada. The 23rd ISNOG will take place in Copenhagen, Denmark, from June 14–17, 2026. This season offers more than 17 hours of daylight, and the symposium will be hosted at the centrally located DGI Byen, in walking distance from Copenhagen Central Station, various hotels and attractions such as Tivoli Gardens. Copenhagen is continuously rated among the happiest and most liveable cities in the world.
Like previous conferences, the 23rd ISNOG will bring together scientists from around the world interested in the chemistry, physics, optics, mechanics, and engineering of non-oxide and new optical glass materials as well as both experimental and computational techniques for their advanced characterization. The conference will be organized into five technical sessions.
We hope to see the participation of both industrial researchers and engineers, experts from academia and students to promote discussions and exchanges of knowledge. Through plenary sessions and both oral and poster presentations, we aim to create an open atmosphere that allows new collaborations and friendships to be formed and ideas to be shared and discussed. We look forward to seeing you in Copenhagen!
