GOODMAN Updates - Mar 2024:
  • New Goodman feature prevents an exposure being started if the Goodman Acquisition Camera (GACAM) arm is in the IN position.
  • A new grating is available for Goodman: the 1200CaNIR grating is optimized for the Ca II triplet at 8498, 8542, 8662 A. This grating is now supported in AEON-mode.

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)
