Integration, commissioning and performance of the UK FMOS spectrograph
Proceedings of SPIE - The International Society for Optical Engineering 7014 (2008)
Abstract:
The UK FMOS spectrograph forms part of Subaru's FMOS multi-object infrared spectroscopy facility. The spectrograph was shipped to Hilo in component form in August of 2007. We describe the integration sequence for the spectrograph, the results of cooldown tests using a new chiller unit fitted to the spectrograph at the telescope, and alignment tests of the spectrograph, gratings and OH-suppression masks. We present the first-light observations for the spectrograph from May 2008.Management of optical interfaces in the VLT KMOS instrument
Proceedings of SPIE - The International Society for Optical Engineering 7017 (2008)
Abstract:
The heart of the KMOS instrument is a complex optical system with over 300 separate optical paths. The optical design is spread between 4 sub-systems which have been designed at three different institutions. In order that the end to end performance of the final design can be monitored and controlled it is necessary to specify the performance and interface requirements of each sub-system clearly. This paper describes the parameters that were necessary to control so that the sub-system designs could be carried out independently while maintaining visibility and control of the end to end performance. The method of apportioning the budgets between the sub-systems and the modeling performed to verify compliance is also described.Design of the KMOS multi-object integral field spectrograph
Proceedings of SPIE - The International Society for Optical Engineering 6269 I (2006)
Abstract:
KMOS is a near-infrared multi-object integral field spectrometer which has been selected as one of a suite of second-generation instruments to be constructed for the ESO VLT in Chile. The instrument will be built by a consortium of UK and German institutes working in partnership with ESO and is currently at the end of its preliminary design phase. We present the design status of KMOS and discuss the most novel technical aspects and the compliance with the technical specification.FMOS: The fiber multiple-object spectrograph IV: Current status of OHS-based spectrograph
Proceedings of SPIE - The International Society for Optical Engineering 6269 I (2006)
Abstract:
The Fiber Multiple-Object Spectrograph for Subaru Telescope (FMOS) is quite large instrument composed of the prime focus unit, the fiber bundle unit, and the two infrared spectrographs. Among these units, a part of the prime focus unit and one of the spectrograph were transported from Kyoto University to the Subaru observatory in the middle of 2005. We present the optical and the mechanical components of the spectrograph, which was reassembled on the new floor of the Subaru dome. We also show the preliminary results of the optical alignment and the cooling test of the instrument at the summit of Mauna Kea.Opto-mechanical design of the KMOS spectrograph module
