Abstract :
In this paper, the optical design of astronomical detector array with SIS for 600-700 GHz is proposed. A unit has 127 pixel, and SIS junctions are coupled to double slot antennas and extended hemisphere lens made from Silicon or Alumina ceramics. A lens with multi-pixel system is compared to 1 lens with 1 antenna system (fly-eye)from the view point of antenna spacing, aberration, and beam efficiency.
