Abstract

The High Resolution Optical Spectrograph (HROS) will operate at the Cassegrain focus of the Gemini South telescope, at a resolving power of R equals 50,000. It will use an immersed echelle for dispersion, and fused-silica prisms for cross- dispersion. The instrument will weigh two tonnes and will need to meet stringent engineering performance requirements. This paper describes these requirements and the engineering approach used in the HROS design.
