AbstractThe instrument group of the Herzberg Institute of Astrophysics has been commissioned by the Gemini Observatory to participate in a competitive conceptual design study for a new Gemini High-Resolution Optical Spectrograph (GHOS). Concurrently this same group is working in partnership with both the Gemini and CFH Telescopes to design the Gemini Remote Access to CFHT ESPaDOnS Spectrograph, (GRACES). Both these instruments will use a fiber feed allowing light received by the Gemini telescope to be processed via remotely positioned instruments. This paper will explore the similarities and differences in requirements, inherent challenges, concepts, design solutions and areas of concept sharing. © 2012 SPIE.
