Abstract: SITELLE is a new imaging Fourier transform spectrometer to be installed at the Canada-France- Hawaii Telescope. The development of its dedicated performance model drives the design of the instrument and the flow down of the science cases requirements into system requirements. First, the selected configuration with off-axis flat mirrors makes the achievement of a high efficiency in the near ultra violet easier. Secondly, servomechanism’s desirable performances were defined in order to design a photon noise limited instrument, based on a relevant scene. These performances should be maintained during a 4 hours data-cube acquisition, under operational vibrations and external effects such as wind gust hitting the telescope. Ultimately, this instrument performance model is the core of the signal to noise ratio simulator that will help observers to evaluate the potential benefits of SITELLE for their target.
