A device for the optical measurement of an optical system, in particular an optical imaging system, is provided. The device includes at least one test optics component arranged on an object side or an image side of the optical system. An immersion fluid is adjacent to at least one of the test optics components. A container for use in this device, a microlithography projection exposure machine equipped with this device, and a method which can be carried out with the aid of this device are also provided. The device and method provide for optical measurement of microlithography projection objectives with high numerical apertures by using wavefront detection with shearing or point diffraction interferometry, or a Moir� measuring technique.
It goes without saying that the device shown is suitable for measuring not only a projection objective, but also any other desired optical imaging systems and other optical systems by means of Moir� measurement technology. The invention also comprises devices which are based on other conventional measuring techniques for determining aberrations of optical imaging systems and which make use of a periodic structure to be arranged on the object side and/or image side, in order to generate a superimposition pattern or interference pattern indicating aberrations. The invention is suitable for all normally used radiation wavelengths, such as for the use of an He—Ne laser at 632.8 nm, and other light sources such as are customary in lithography, in particular including those in the UV wavelength region and EUV wavelength region between 10 nm and 300 nm.
