We have developed a special optics with a β∗ of 1000m for two interaction regions (IR1 and IR5) in the LHC, to produce very low divergence beams required for elastic proton-proton scattering. We describe the design, commissioning and operation of this optics in the LHC. The β∗ of 1000 m was reached by de-squeezing the beams using 17 intermediate steps beyond the β∗ of 90 m, which had been the previous highest β∗ value reached in the LHC. The optics was measured and the β-beating globally corrected to a level of 10%.
