Abstract: A contamination barrier that passes through radiation from a radiation source and captures debris coming from the radiation source is disclosed. The contamination barrier includes an inner ring, an outer ring, and a plurality of lamellas. The lamellas extend in a radial direction from a main axis, and each of the lamellas is positioned in a respective plane that include the main axis. At least one outer end of each of the lamellas is slidably connected to at least one of the inner and outer ring.
