Abstract
The spatial structure of an optical element is determined. The optical element has a first optically active surface and a second optically active surface. The optical element is arranged in a holding device. The position of a point (P) on the first optically active surface and the position of a point (P') on the second optically active surface are referenced in a coordinate system fixed to the holding device. The topography of the first optically active surface is determined in a coordinate system referenced to the holding device by the position of point (P) and the spatial structure of the optical element is calculated from the topography of the first optically active surface and from a data set as to the topography of the second optically active surface. The data set is referenced to the fixed coordinate system of the holding device by the position of point (P′).
