Description:

A 220-fiber spectrometer available at the f/8.8 Ritchey-Chretien focus. The spectrometer has 10 A resolution in the bandpass 3,900-7,600 A. Fibers are inserted by hand into a drilled plate prepared from accurate celestial coordinates prior to the run. The diameter of the field available to the fibers is 66 arcminutes and the closest positioning of two fibers is 10 arcsec. The spectrometer has a dedicated AR-coated TK 1,024x1,024 CCD with high optical QE and low noise. Alternately, the spectrometer may be used with TK4.
