The overall optical design of X-Shooter, the second generation, wide band, intermediate resolution, high efficiency, three-arms spectrograph for the VLT, is presented. We focus on the optical design of the three optimized arms, covering UVB (300-550 nm), VIS (550-1000 nm), and NIR (1000-2300 nm) wavelength ranges, including spectrographs and pre-slit optics. All spectrographs share the same original "4C" concept (Collimator Correction of Camera Chromatism). We describe also the auxiliary optics, such as dichroics, acquisition and guiding unit. Performances analysis are summarized.
