    Abstract: An optical arrangement, e.g. a projection exposure apparatus (1) for EUV lithography, includes: a housing (2) enclosing an interior space (15); at least one, preferably reflective optical element (4-10, 12, 14.1-14.6) arranged in the housing (2); at least one vacuum generating unit (3) for the interior space (15) of the housing (2); and at least one vacuum housing (18, 18.1-18.10) arranged in the interior space (15) and enclosing at least the optical surface (17, 17.1, 17.2) of the optical element (4-10, 12, 14.1-14.5). A contamination reduction unit is associated with the vacuum housing (18.1-18.10) and reduces the partial pressure of contaminating substances, in particular of water and/or hydrocarbons, at least in close proximity to the optical surface (17, 17.1, 17.2) in relation to the partial pressure of the contaminating substances in the interior space (15).
