The Telescopio Nazionale Galileo (TNG) is able to offer an F/11 Nasmyth focal station with an easy mount for small devices or compact instruments. The slit masks at the focal plane of the LRS spectrograph can be removed in few minutes from the selector stage. A FoV of ~9x9arcmin2 is available and a small instrument can be mounted instead of the slit on a mechanical interface of 240x125mm. The size of the instrument along the optical axis is limited by the support of the collimation lens of the spectrograph. This solution has already been used for small devices like a CCD camera or a SH sensor and a compact Hamamatsu photometer. Furthermore from 2016 it will host the folding optical relay for the GIARPS Instrument. This interface is an opportunity to test new instruments, prototypes or demonstrators in a not invasive or time consuming manner at a 4m class telescope.
