Method for producing a wavefront-corrected optical arrangement consisting of at least two optical elements, in which in a step a), a total wavefront error of the optical arrangement is determined, in a step b), the total wavefront error is compared with a permissible tolerance range of the total wavefront error, in a step c), at least one of the optical elements is selected if the permissible tolerance range is exceeded, and in a step d), the optical properties of the at least one selected optical element are changed such that the determined total wavefront error of the optical arrangement is within the permissible tolerance range, characterized in that - before step a): - in a step a-2), the optical elements are individualized by each being assigned an individual identifier such that individualized optical elements (2.1B to 2.1H) are present and, from all the individualized optical elements (2.1B to 2.1H), individual surface errors are measured with the correct coordinates and the measured individual surface errors are stored with the correct coordinates so as to be assigned to the particular individualized optical element (2.1B to 2.1H), and - in a step a-1), the optical arrangement comprising the individualized optical elements (2.1B to 2.1H) is produced virtually as a virtual optical arrangement, - in step a), the total wavefront error of the virtual optical arrangement is determined by means of a calculation from the individual surface errors, and a calculated total wavefront error is obtained, the total wavefront error being the totality of wavefront errors over all field points, such that it is possible to correct the total wavefront error simultaneously for all field points; - in step b), the calculated total wavefront error is compared with the permissible tolerance range of the total wavefront error, - in step d), the optical properties of the at least one selected individualized optical element (2.1B to 2.1H) are virtually changed such that the calculated total wavefront error of the virtual optical arrangement is within the permissible tolerance range, - in a step e), the changes made virtually to the optical properties of the at least one selected individualized optical element (2.1B to 2.1H) are stored as processing data and made available such that they can be retrieved repeatedly, and - in a step f), the at least one selected individualized optical element (2.1B to 2.1H) is processed according to the processing data and the optical arrangement comprising the individualized optical elements (2.1B to 2.1H) is produced. - before step a): - in a step a-2), the optical elements are individualized by each being assigned an individual identifier such that individualized optical elements (2.1B to 2.1H) are present and, from all the individualized optical elements (2.1B to 2.1H), individual surface errors are measured with the correct coordinates and the measured individual surface errors are stored with the correct coordinates so as to be assigned to the particular individualized optical element (2.1B to 2.1H), and - in a step a-1), the optical arrangement comprising the individualized optical elements (2.1B to 2.1H) is produced virtually as a virtual optical arrangement, - in a step a-2), the optical elements are individualized by each being assigned an individual identifier such that individualized optical elements (2.1B to 2.1H) are present and, from all the individualized optical elements (2.1B to 2.1H), individual surface errors are measured with the correct coordinates and the measured individual surface errors are stored with the correct coordinates so as to be assigned to the particular individualized optical element (2.1B to 2.1H), and - in a step a-1), the optical arrangement comprising the individualized optical elements (2.1B to 2.1H) is produced virtually as a virtual optical arrangement, - in step a), the total wavefront error of the virtual optical arrangement is determined by means of a calculation from the individual surface errors, and a calculated total wavefront error is obtained, the total wavefront error being the totality of wavefront errors over all field points, such that it is possible to correct the total wavefront error simultaneously for all field points;
