Conference on Ground-Based and Airborne Instrumentation for Astronomy (VI. 2016. Edinburgh, Scotland)MEGARA (Multi-Espectrografo en GTC de Alta Resolucion para Astronomia) is the future optical Integral-Field Unit (IFU) and Multi-Object Spectrograph (MOS) for the GTC 10.4m telescope. The spectrograph is currently being integrated in the laboratory for a pre-shipping review in September 2016. This paper presents the current status and final performance of the spectrograph mechanics and opto-mechanics, composed of the mechanisms and the large optomechanical elements mounts.engjournal articlehttp://dx.doi.org/10.1117/12.2233041http://proceedings.spiedigitallibrary.org/open access52MEGARAGTCMechanical designMechanismSpectrographOpto-mechanicsAstrofísicaAstronomía (Física)
