The multiprism device is a crucial component of the Espresso Anamorphic pupil Slicer (APSU). At the end of the slicer, is necessary to differently fold each field to correctly illuminate the echelle. The solution is made by gluing cylindrical prisms with proper bending low angle onto a support double plate silica window. We present here the integrated robotic system conceived to reach the required tolerances in term of alignment and Integration. It consist in a tip tilt stage to select the folding angle, coupled to an x-y stage to position the elements and a z axis to perform the gluing.
