Abstract:
Disclosed is a suppression filter having a profile defining at least two reflective surface levels, each reflected surface level being separated by a separation distance. The separation distance is such that the reflective suppression filter is operable to substantially prevent specular reflection of radiation at a first wavelength and at a second wavelength incident on said reflective suppression filter. Also disclosed is a radiation collector, radiation source and lithographic apparatus comprising such a suppression filter, and to a method of determining a separation distance between at least two reflective surface levels of a suppression filter.

Claim (Index 42):
The radiation collector of  claim 41 , wherein the separation distance is close to proportional to a first odd number of half the first wavelength and as close to proportional to a second odd number of half the second wavelength.
