(a) Surface profile of the measured bent crystal using a stitching interferometer. The high-spatial-frequency data are filtered. (b) The main part of the fitted hyperbolic-paraboloid surface (saddle surface). The surface equation is z = (y − yc)2 / 2Ry − (x − xc)2 / 2Rx + c(x − xc)(y − yc) + f. (c) The regular cubic term of the fitted measured surface is z = a(x − xc)3. This term can be explained by the unequal couples applied on each end of the crystal slab. (d) The fitting errors of the measured surface.
