Available Optics List

  Last Up Date  2003.9.1

These are lists of filters, slits, lenses, windows, and gratings for COMICS. Some filters are still under construction. COMICS filter wheels have a finite set of positions for filters and the number of filters is larger than that of filters installed at once. This situation is the same for slits.
