Abstract
A calibration facility of laboratory size and modular in design is described for absolute spectral reflectivity and spatial resolution in image-forming devices. It is based on an optical table concept where all optical elements can be modularly positioned on remotely controlled translation/rotation stages. XUV photons are provided by a minifocus conventional source with replaceable anode. K-, L-, and M- band transition radiation from different metals is used. This source can be positioned at variable distances (up to 5 m) from the measurement chamber for imaging purposes. Spectral control of the radiation used in the tests can be achieved with transmission filters, with grazing incidence reflections or with a grazing incidence monochromator. Channeltron detectors in photon counting mode monitor incident and reflected signals. This instrument is now being used for characterizing grazing incidence flat mirrors as well as multilayer-coated optical surfaces.
