An overall view of the Frascati Tokamak Upgrade (F.T.U.) Thomson scattering system is illustrated and particular attention is paid to the optical and spectral analysis equipments. The system includes the laser source, the collection optics, a set of filter polychromators, all the electronic equipments necessary to collect the data relevant to the scattered light and to send them to the F.T.U. data acquisition system. The features of this system can be summarized as follows: rejection to laser wavelength: ≥107, laser energy: ≥5 J, overall optical efficiency: ≥40%, and capability of multiple time and space measurements on the Thomson scattered light.
