The CLEO Hub — The Exhibition Reimagined

The CLEO Hub is your destination for product information, industry and market-based knowledge and networking opportunities.


In 2022, CLEO presented a global representation of  70 participating companies including Coherent, Inc., Menlo Systems, MKS Instruments, Thorlabs, Inc., Toptica and many more. In 2023, we expect an even larger exhibition with the essential product information you need to advance and facilitate your research.

Show Floor Theater 

A dedicated theater space in the exhibition hosts technical programs (Plenary Sessions I and II and select Applications & Technology Topical Reviews); state-of-the-market business sessions and product demonstrations.


The CLEO Hub offers numerous opportunities to enhance your professional connections. Lounge space for attendees, plus a dedicated lounge just for student attendees, provide respites from a busy conference schedule.
