Important: Current Status Report
Subaru Telescope has a suite of eight facility instruments
providing imaging and spectroscopic capabilities over the full range
of wavelengths from optical to mid-infrared.
- AO188 - Subaru 188-elements Adaptive Optics system - delivers diffraction-limited images in the near-infrared.
- COMICS - Cooled Mid-Infrared Camera and Spectrograph - provides imaging and spectroscopy from 7.5-25 microns.
- FOCAS - Faint Object Camera And Spectrograph - provides optical imaging and longslit and multi-slit spectroscopy over a 6 arcmin field of view.
- HDS - High Dispersion Spectrograph - provides extremely high-resolution optical spectroscopy.
- HSC - Hyper Suprime-Cam - provides optical imaging over a very large field of view (1.5 degree diameter) with a mosaic of CCDs.
- IRCS - Infrared Camera and Spectrograph - provides high-angular resolution imaging combined with AO188, low-resolution grism and high-resolution echelle spectroscopies over 0.9-5.6 microns.
- MOIRCS - Multi-Object Infrared Camera and Spectrograph - provides imaging and low-resolution spectroscopy from 0.9-2.5 microns over a 4 arcmin x 7 arcmin field of view.
Visiting instruments* (Procedures to carry-in Visiting instruments )
- CHARIS - Coronagraphic High Angular Resolution Imaging Spectrograph - provides high contrast images of exoplanets, disks, brown dwarfs with SCExAO+AO188.
- HiCIAO - High Contrast Instrument for the Subaru Next Generation Adaptive Optics - provides a near-infrared imaging capability in the vicinity of bright sources. Although HiCIAO+AO188 has been extensively used in the SEEDS project and openuse programs, this mode is no longer available since S16B. HiCIAO will be used as a camera combined with SCExAO only.
- SCExAO - Subaru Coronagraphic Extreme Adaptive Optics - delivers high contrast images of the innermost surrounding of bright sources to HiCIAO and CHARIS.
(*) Observing proposals using the visiting instruments must include the relevant instrument PI as a Co-investigator.
- AO36 - Subaru 36-elements Adaptive Optics system - delivers diffraction-limited images in the near-infrared.
- CIAO - Coronagraphic Imager - provides a near-infrared imaging capability in the vicinity of bright sources.
- CISCO/OHS - Cooled Infrared Spectrograph and Camera for OHS - provides imaging and low-resolution spectroscopy in the near-infrared.
- FMOS - Fiber Multi Object Spectrograph - provides fiber-fed multi-object spectroscopy from 0.9-1.8 microns over a 30 arcmin field of view.
- Kyoto3DII - Kyoto tridimensional spectrograph II - provides Fabry-Perot / filter imaging and integral field / long-slit spectroscopy in the optical (opening until S17A).
- RAVEN - Multi-Object Adaptive Optics(MOAO) demonstrator - delivers diffraction limited images in 2 science channels to IRCS.
- Suprime-Cam - Subaru Prime Focus Camera - provides optical imaging over a large field of view with a mosaic of CCDs (opening until S17A).
