| DESCRIPTION |
The Goodman High Throughput Spectrograph (GTHS) was built in the Goodman Laboratoryat the University of North Carolina under the leadership of Prof. J. ChristopherClemens. It is an imaging spectrograph, capable of producing excellent image qualityacross a 7.2 arcmin diameter FOV (with a 0.15 arcsec/pixel scale), and spectra atvarious resolutions from the atmospheric UV cutoff all the way out to 850nm. Itemploys all transmissive optics, and Volume Phase Holographic (VPH) Gratings toachieve the highest possible throughput for low resolution spectroscopy over the320-850 nm wavelength range. The paper describing the instrument is Clemens et al.(2004). In spectroscopic mode the Goodman Spectrograph can obtain both single, longslitspectra and spectra of multiple objects simultaneously over a field of 3.0 x 5.0arcminutes using multi-slit masks. A carousel style mask changer, holding up to 36masks allows the slit plates to be interchanged and located at the instrumententrance aperture.In imaging mode the plate scale is 0.15 arcsec/pixel and the field of view is 7.2arcmin in diameter (3096 x 3096 unbinned pixels).
