SPIE Astronomical Telescopes + Instrumentation

From concept to cosmos: engineering the future of astronomy through global collaboration

Hear the latest advances in astronomical engineering from leading experts. Join colleagues in Copenhagen.

We look forward to gathering 5–10 July 2026 in Copenhagen, Denmark, for SPIE Astronomical Telescopes + Instrumentation, the most valuable technical event for ground-based, airborne, and space-based telescopes, and their supporting instrumentation. With a strong program and an active community, this event allows researchers and engineers to share advancements, discoveries, challenges, and project updates with colleagues from around the world.
