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:
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.
