Summary:In an embodiment, multiple conjugate planes are used to create a plurality of optical pupil planes and a plurality of image planes. These optical planes solve multiple problems and introduce significant performance enhancements in the system. In one implementation of a disclosed embodiment, the measurement channel is based on the reverse Shack-Hartmann principle. By introducing a relay system (for example a 4-f lens system) the slit plane could be made conjugate to the measured system pupil plane (unlike a previous implementation where the slits were places away from the pupil plane as it was not accessible directly). Creating a virtual pupil plane allows for more accurate placement of the plane without the need for contact with the measured optical system.
