We will present a new instrument, REACH (Rigorous Exoplanetary Atmosphere Characterization with High dispersion coronography) to realize very high spectral resolution, over R=100,000 at extreme contrast by combining the high-resolution spectrograph InfraRed Doppler (IRD) and the extreme adaptive optics instrument, SCExAO at the Subaru Telescope. REACH consists of mini-IFU like 7 single-mode fiber bundle located at a focus of SCExAO, a high-speed photometric monitoring camera, and a beam switching and feed system from the fiber bundle to IRD’s 2 single-mode fibers. We will provide an overview of the instrument and present the recent results from on-sky tests.
