About AAO

Global leader in astronomical instrumentation

Australian Astronomical Optics is working at the forefront of astronomical optics. From photonics and positioning systems to astronomy data management and research.

Our History - 50+ Years of Excellence

Australian Astronomical Optics (AAO) has evolved over five decades, with each chapter strengthening its legacy of world-leading astronomical innovation.

Established in 1974 as a bi-national facility of the Australian and UK governments, AAO became fully Australian Government-owned in 2010. In 2018, it transitioned into two entities: AAO at Macquarie University, focused on instrumentation, research and data management; and telescope operations at Siding Spring Observatory, now operated by the Australian National University.

Today AAO is a special department within the Faculty of Science and Engineering, focusing on designing, building, and testing advanced instrumentation for astronomical studies of deep space, as well as Earth observation, defence, space exploration, and medical photonics.

AAO has built a global reputation in telescope instrumentation, developing instruments for the Anglo-Australian Telescope and major telescopes worldwide. Its pioneering use of optical fibres helped transform multi-fibre spectroscopy into a powerful scientific tool.

In 2026, AAO moved into a purpose-built facility in Macquarie University’s Engineering Innovation Building, supporting every stage of instrument development from optical design and prototyping to integration, testing, cryogenics and space qualification.

Strategic Plan - Bridging Eras

AAO is ambitiously bridging eras to shape a future of global leadership in scientific instrumentation and research, driving impact and inspiring the next generation through strategic collaboration and innovation.

National Instrumentation Partnerships

AAO is both a department within the Faculty of Science and Engineering and a founding partner in the Astralis Instrumentation Consortium(Astralis).

Under the banner Astralis Instrumentation Consortium (Astralis), Macquarie University is partnering with the Australian National University (ANU), the University of Sydney (USYD) and Astronomy Australia Ltd (AAL) to establish the Australia's national capability for astronomical instrumentation. Macquarie University is excited to take a significant role in growing Australia’s global position in astronomical instrumentation.
