Paper Abstract

The concept design of the faint object camera and spectrograph (FOCAS) for the 8.2 m SUBARU telescope (JNLT) is presented. The FOCAS is designed for enabling observations of extremely faint galaxies distributed over a 6 arcmin FOV with spectral resolution of R equals 1000. Fully transmitting optics will produce high quality images better than about 20 micrometers rms diameter over the entire FOV in white light of a wavelength range of 0.365 - 0.9 micrometers . A pair of abuttable CCDs with 4000 x 2000 pixels of 15 micrometers square pixel size are considered to be used. Several observing modes are available with the automated multislit assembly and changable optical elements. Control software coupled with telescope control software enables an automatic observation of several tens of galaxies simultaneously.
