                      system on the ITER plasma core (CXRS core) will provide
                      spatially resolved measurements of plasma parameters. The
                      optical front-end is located in upper port 3 and the light
                      of 460–665 nm is routed to spectrometers housed in the
                      tritium building. This paper describes the layout of the
                      optical system in the port plug, cell and interspace areas.
                      The layout is a continuation of the developments described
                      in [1] and takes into account changes in the design of the
                      upper port plug, considerations for the system lifetime as
                      well as internal and external tolerances on the optical
                      chain. The layout was selected also with a number of
                      additional criteria, including optical performance,
                      radiation shielding, maintainability and robustness. A
                      free-space optical chain was added pushing the optical
                      fibres to the port cell. A line-of-sight finder imaging
                      apertures and masks in the optical chain was added to enable
                      determination of deviations within the optical chain and
                      stabilise the image on the fibres. Where feasible, existing
                      solutions for sub-systems such as the shutter were adapted
                      to the layout.},
