ATLAS is the future Laser Tomographic AO system of the E-ELT. Its goal is to provide a diffraction limited PSF in K band for a significant part of the sky (typically more than 60%). A first concept of the module combined with optomechanical implementation and associated performance is presented. Results show the feasibility of the concept, its versatility and a relative simplicity which is a good first step toward a potential implementation in the early time of the telescope.
