Device and method for measuring imaging properties of an optical system

A device for measuring imaging properties of an optical system, the device comprising:

• a rigid holding device;
• and
• a plurality of MTF measuring devices arranged at predefined positions of the holding device such that, by each of the plurality of MTF measuring devices, a modulation transfer function can be measured at respective different, predefinable, angular positions in the image field of the optical system,
• wherein the holding device comprises at least a first holder and a second holder,
• wherein the plurality of MTF measuring devices comprises a first group and a second group of MTF measuring devices,
• wherein the first holder is configured to hold the plurality of MTF measuring devices of the first group at first positions so that the plurality of MTF measuring devices of the first group are arranged on the first holder on a first spherical shell,
• wherein the second holder is configured to hold the plurality of MTF measuring devices of the second group at second positions so that the plurality of MTF measuring devices of the second group are arranged on the second holder on a second spherical shell, and
• wherein the first spherical shell and the second spherical shell have different radii and are arranged so as to be mutually concentric.
