METHOD FOR PRODUCING A CONCAVE / CONVEX GRID FOR A MONOCHROMATOR AND SUCH A GRID

摘要

Method for producing a concave or convex grating (1) for a monochromator. In order not to be subject to restrictions with regard to a specific wavelength in the design of the grid and also to be able to produce a blaze grating without a subsequent manufacturing step, it is provided according to the invention that the method comprises the calculation of coordinates of grid points (6) of grid lines (2) a rotating body (3) by defining intersections of a family of auxiliary surfaces with a surface of the rotating body (3), the array of auxiliary surfaces being rotated by a family of second order curves rotating about an axis of rotation (x) of the rotating body (3) , the method further comprising feeding the coordinates of the intersections or lattice points (6) into a computer-controlled ultra-precision lathe, around a lattice structure, the circles centered about the rotation axis (x) or a spiral running around the rotation axis (10), to rotate in a base body, at least in sections, the F orm of the rotary body (3).
