GOODMAN NEWS - Feb 2019: During the recent Feb 19, 2019 the round GG-385 order-sorting filter broke beyond repair. While we obtain a replacement, we have available a 4x4 inch GG-395 on loan from the COSMOS instrument on the CTIO 4m Blanco telescope. Users interested in this filter should request it specifically in the Instrument Setup form.

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)
