Due to the deformations caused by the thermal and clamping of the monochromator, the beamline optical focus will be shifted in the horizontal or vertical direction. Then compensation device needs to be added to make the focus align with the sample position. The correction tablet uses 1D compound refractive lens (CRL), which is fixed on a customized five-dimensional manipulator. According to different errors corresponding to different energies, the correction tablet needs to rotate at different angles. If only the rotation angle cannot meet the requirements, a more appropriate CRL should be chose by switching, Generally in the horizontal direction through a large stroke to achieve. When cooling is required, the clamping block of the 1D CRL is made of Cu material with good heat transfer effect, and the displacement compensation of rotation is carried out by copper foil.
