| 摘要 |
The invention relates to a method for correcting a surface shape of a reflective optical element (1) which has a substrate (2) and a reflective coating (3), wherein the method comprises at least the following step: correcting the surface shape (5) by generating a permanent local shape variation (10) in at least one deformable layer (7) which is arranged between the substrate (2) and the reflective coating (3), and which has a magnetic shape memory alloy, wherein the permanent local shape variation (10) is generated by applying an electromagnetic field, in particular a magnetic field (9), to the at least one deformable layer (7). The invention also relates to a reflective optical element (1) comprising a substrate (2), a reflective coating (3), and at least one deformable layer (7) arranged between the substrate (2) and the reflective coating (3), and having a magnetic shape memory alloy. |
