Instrumentation and Detectors

Precision astronomical observations require the most sensitive instrumentation and detectors possible. Modern telescopes need to maximize the quality of the images they receive, while studying objects that are incredibly faint.

Steward Observatory is world renowned for developing state of the art instrumentation, which can be found on many of the leading telescopes in the world.

Faculty and Research Staff with a research interest in this area include:


(Bottom Right) Professor Laird Close and his team have achieved excellent AO images in the visible (55% Strehls at i' --765 nm)) in the test tower in Italy with the MagAO system running in full 800Hz closed loop (400 modes) on R=8 star in 0.8" seeing (V band) and in simulated 33 mph winds.
