Abstract
Official abstract text for this publication.
An optical system has a housing with a mount and an opening to a receiving region, the receiving region being located within the housing and including the mount. At least one optical element is inserted into and removed from the receiving region through the opening, and at least one gas supply device provides a flow of gas in the receiving region. Alternatively or in addition, the optical system has a gas lock that receives the optical element. The opening interconnects the gas lock and the receiving region of the housing, and accommodates passage of the optical element between the gas lock and the receiving region.
