The Quest Large Area Camera Overview
A large area CCD camera has been designed and constructed at Yale
University
and Indiana University specifically to operate at the prime focus of
the
Palomar Oshin Schmidt Telescope. The array consists of 112 CCD's
(4 rows of 28 CCD's each) and covers the full field of view of the
telescope
(3.6 o x 4.6o). The CCD's are thinned, back
illuminate 600 x 2400 13µ x 13µ pixel devices fabricated at
the Sarnoff Laboratories. The camera is designed to operate
either
in the Drift Scan or a Point and Stare mode. Each of the four
rows
of CCD's has a color filter in front of it with different Johnson or
Gunn
bands. Thus in the Drift Scan mode data in four different colors
can be obtained essentially simultaneously.
