CSHELL is a 1 - 5.5 micron high resolution single-order echelle spectrograph
which uses a 256 x 256 pixel InSb detector array. Each pixel is 0.2 arcsec
on the sky and the spectroscopic dispersion is 100,000 per pixel. Slits
from 4.0 - 0.5 arcsec provide spectral resolutions of up to 30,000. CSHELL
also has an IR imaging mode for source acquisition which covers a 30 x 30
arcsec field. An internal CCD (1 arcmin field) allows autoguiding.
