SPIE Astronomical Telescopes + Instrumentation

Research for ground- and space-based telescopes, supporting technologies, and instrumentation

Advancing astronomical engineering | Call for Papers opens soon

This community does outstanding work. 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. The 2026 call for papers opens in late September 2025, and we encourage researchers and engineers to share advancements, discoveries, challenges, and project updates with the community.
