| Research Abstract |
The main goal of this project was to develop and fabricate an ultra-wide imager (named Hyper Suprim-Cam: HSC) mounted on the prime focus of Subaru Telescope at Mauna Kea, Hawaii. Very challenging development items such as huge aspherical lenses, highly stiff and light-weighted fine ceramics needed for lens barrel, high QE large format CCD, etc. have been all successfully cleared, and HSC camera has been manufactured and mounted on Subaru Telescope to open to the starlight. First preliminary results reveal the very high image quality (better than 0.5 arc-seconds) over the entire field of view of 1.5 degrees, promising perspective to lead world-wide research programs of Dark Energy & Dark Matter by providing extremely accurate images and their analyzed data of millions of remote galaxies.
