Paper Abstract

We present the design of an echelle spectrograph based on commercially available components. This instrument is an ideal solution to equip small telescopes with low cost but scientifically effective instrumentation. The spectrograph is fiber fed, reaches a resolution of about 8,000, can be located in a gravity invariant and thermally controlled environment and can be used for the long term spectroscopic monitoring of bright objects. The optical design and performances of the instrument are analyzed using Zemax, we present an option for the mechanical design too.
