(a) Schematic of the bending mechanism when the crystal is bent. OA and OB are the rotation axes of two arms, E and F are on the midpoint of two pairs of rollers. By setting OAOB = 2OAE = 2OBF, the centre of the crystal can be approximately fixed when changing bending radii. (b) Assembly engineering drawing of the sagittal bender. |
