Ítem EMIR mechanical design status(SPIE-INT SOC OPTICAL ENGINEERING, 2004-09-01) Fuentes, F. J; Sánchez, Vicente; Barrera, Sonia; Correa, Santiago; Pérez, Jaime; Redondo, Pablo; R. Restrepo; Tenegi, Fabio; Villegas, Alejandro; Patrón, Jesus; Garzón, Francisco; Universidad EAFIT. Departamento de Ciencias Básicas; Óptica AplicadaEMIR is the NIR multi-object imager and spectrograph for the GTC (Gran Telescopio Canarias). The instrument PDR phase was held successfully in March 2003, and we are at present in the middle of the ADR (Advanced Design Phase) during which a number of mechÍtem EMIR optomechanics(SPIE-INT SOC OPTICAL ENGINEERING, 2004-09-01) Barrera, Sonia; Villegas, Alejandro; Fuentes, Javier; Correa, Santiago; Pérez, Jaime; Redondo, Pablo; R. Restrepo; Sánchez, Vicente; Tenegi, Fabio; Garzón, Francisco; Patrón, Jesus; Universidad EAFIT. Departamento de Ciencias Básicas; Óptica AplicadaEMIR is a NIR multiobject spectrograph with imaging capabilities to be used at the GTC. A general description of instrument performances, as well as the updated optical and mechanical layouts, can be found elsewhere on these proceedings.Ítem EMIR: the GTC NIR multi-object imager spectrograph(SPIE-INT SOC OPTICAL ENGINEERING, 2004-09-01) Garzón, Francisco; Abreu, David; Barrera, Sonia; Correa, Santiago; Díaz, Jose; Fragoso, Ana; Fuentes, F.J; Gago, Fernando; Gonzalez, Carlos; López, Pablo; Manescau, Antonio; Patrón, Jesus; Pérez, Jaime; Redondo, Pablo; R. Restrepo; Sánchez, Vicente; Villegas, Alejandro; Universidad EAFIT. Departamento de Ciencias Básicas; Óptica AplicadaWe present the final global design and performances of EMIR, the NIR multi-object spectrograph of the GTC, as well as the plan for its early scientific exploitation.Ítem Structural and thermal analysis of EMIR(SPIE-INT SOC OPTICAL ENGINEERING, 2004-09-30) Correa, Santiago; R.
