SCExAO is the premier high-contrast system in the Northern Hemisphere. It provides high Strehl ratios at near-IR wavelengths (y-K band) with stable pointing and coronagraphs with extremely small inner working angles, optimized for imaging faint exoplanets and brown dwarfs very close to their host stars. In the visible, it has several interferometric imagers which offer polarimetric and spectroscopic capabilities and spectral differential imaging. The RHEA spectrograph obtains spatially resolved, high resolution spectroscopy in the visible for the first time. A recent addition to the NIR arm is the CHARIS integral field spectrograph, which is nearing the end of commissioning. We also describe our single mode fiber injection which is used to feed a compact photonic spectrograph that could be useful for future ELT instrumentation. New capabilities on the horizon include post-coronagraphic spectroscopy, nulling interferometry and an MKID array. Here we present the SCExAO instrument, give an overview of the latest science results and outline a path to the future. |
