Subaru Telescope

(8.2 meter telescope in Hawaii)

Subaru Telescope is an 8 meter Reflector Telescope of the National Astronomical Observatory of Japan, in Hawaii on Mauna Kea. It opened in 1998 and had the largest Monolithic Mirror until surpassed in 2005. Instruments:

  • MOIRCS - Multi-Object Infrared Camera and Spectrograph.
  • IRCS - Infrared Camera and Spectrograph.
  • COMICS - Cooled Mid Infrared (MIR) Camera and Spectrograph.
  • FOCAS - Faint Object Camera and Spectrograph.
  • Suprime-Cam - Subaru Prime Focus Camera.
  • HDS - High Dispersion Spectrograph.
  • HiCIAO - High-Contrasts Coronagraphic Imager and Adaptive Optics.
  • HCS (Hyper Suprime-Cam) - replacement for Suprime-Cam.

In development is PFS (for Prime Focus Spectrograph), designed for galaxies surveys for Cosmology research. It will collect Visible Light and Near Infrared (NIR), using 2400 optical fibers to simultaneously observe multiple targets. It has three arms, each covering a different band, that image the same slit plane simultaneously.

The Hyper Suprime-Cam is an enhanced imaging camera with 870 million pixels and a 1.5° Field of View (FOV). It is coming into use in 2017.

SCExAO (for Subaru Coronagraph with Extreme Adaptive Optics (ExAO)) is a plan to add a Coronagraph with Adaptive Optics (AO) and Speckle Suppression capable of imaging Extra Solar Planets.
