Embodiment
[0048] Using the method for modifying the surface of an optical element of the present invention to process a workpiece to be processed comprises the following steps:
[0049] 1. Planning the processing and scanning route
[0050] 1.1 Take a workpiece to be processed, take the center of the workpiece as the coordinate origin, and establish an X-Y rectangular coordinate system; then according to the size of the workpiece, use a square grid composed of intersecting lines parallel to the coordinate axis and equally spaced (each small unit The side length of the grid is about 10mm) to discretize the workpiece into several processing points S; the coordinates of each processing point on the workpiece are marked as S(x i ,y i ), where x i and y i Represents the position of each point on the workpiece in the discrete grid; the discretized surface of the workpiece is as attached Figure 5 shown.
[0051] 1.2 Connect all the processing points with a number of parallel lines parall...
