title = "Active flexure compensation for the HROS spectrograph",
abstract = "The Cassegrain location of the high resolution optical spectrograph (HROS) for the 8-meter Gemini telescope presents a difficult challenge in controlling mechanical flexure. This is especially the case for a high-resolution spectrography, which requires large and heavy optical components. In HROS, to achieve the required spectrum stability of 2.0 micrometers /hr, we developed a closed-loop monitoring and correction system capable of measuring the spectrograph flexure in as it happens and actively compensating for image motion.",
