Abstract
The Fast automatic spectrograph for transient (FAST) is a valuable tool to classify resources and better characterize variable sources. FAST is a low resolution spectrograph with multiple resolving power modes (R ∼ 300 and 1000 at 6500 Å) in the VIS-UV range and with to capability to work in imaging mode. The spectrograph consist of a collimating mirror, reflective gratings, and a five-lenses design camera that offers a field of view of 10 arcmin when working in imaging mode. The instrument will be installed in the PROMPT-7 telescope which is able to operate without human intervention for the follow-up of time-variable sources. In this work, the optical design of the spectrograph, the telescope specifications, and the objects under study will be discussed.
