Du Pont Instruments

  • CCD
    Direct CCD camera, available for direct imaging giving a scale of 0.259″ per pixel over a field of 8.85 arcmin square. See technical specifications.
    Wide field reimaging CCD camera. WFCCD reimages a 25 arc-minute diameter field onto the WF4K CCD camera, with a scale of 0.484 arcsec/pixel. It produces images of approximately two pixels over the full field, and has good transmission from 3800 Å to 9000 Å. Metal slit masks are used to provide a multi-object spectroscopy capability. See technical specifications.
  • Boller & Chivens Spectrograph
    The B & C slit spectrograph uses a Marconi CCD mated to a Bowen Schmidt camera as the detector. When used with the 600 line/mm grating the dispersion is 1.5 Å/pixel with a wavelength coverage of 3100 Å. The spatial scale on the du Pont Telescope is 0.70 arcsec/pixel, and the maximum slit length 271 arcsec. See technical specifications.
  • Echelle
    Echelle spectrograph, it provides simultaneous wavelength coverage from ~3700-7000 Å at a typical resolution of ~40,000. See technical specifications.
  • CAPSCam
    Specialized astrometric camera designed for an astrometric search for Jupiter-like planets.  The camera employs a Rockwell Hawaii-2RG HyViSI array, and the design is optimized for high accuracy astrometry of red dwarf stars. See technical specifications.
  • RetroCam
    Near-IR imager built especially for the Carnegie Supernova Program, but which is generally available to users.  RetroCam employs a Rockwell Hawaii-1 HgCdTe 1024×1024 array. The focal plane scale is 0.201 arcsec/pixel, with a total field size of  3.4 arcmin square. A single filter wheel containing Y, J, and H filters is available. See technical specifications.
