GOODMAN Update - Aug 2019: The original round GG-385 order-sorting filter that broke during the Jan 2019 earthquake has been replaced with a new one, which is permanently installed in the Goodman second filter wheel.  We are no longer using the COSMOS instrument 4x4 inch GG-395.

The Goodman High Throughput Spectrograph (GTHS) was built in the Goodman Laboratory at the University of North Carolina under the leadership of Prof. J. Christopher Clemens. It is an imaging spectrograph, capable of producing excellent image quality across a 7.2 arcmin diameter FOV (with a 0.15 arcsec/pixel scale), and spectra at various resolutions from the atmospheric UV cutoff all the way out to 850nm. It employs all transmissive optics, and Volume Phase Holographic (VPH) Gratings to achieve the highest possible throughput for low resolution spectroscopy over the 320-850 nm wavelength range. The paper describing the instrument is Clemens et al. (2004)
