    摘要: A method and a device for replacing objective parts, especially of a projection or illumination objective for microlithography in which an objective having an objective interior and objective parts provided therein is provided. At least one objective part is replaceably accommodated in the objective. Immediately prior to installation in the objective, the replaceable objective part is cleaned outside the objective interior in at least one cleaning room sealed off from the ambient atmosphere. Immediately after cleaning, the replaceable objective is installed in the objective without contact with the normal ambient atmosphere.

    摘要: There is provided an optical element module comprising a first optical element and an optical element holder. The first optical element has a first coefficient of thermal expansion. The optical element holder holds the first optical element and has a second coefficient of thermal expansion, the second coefficient of thermal expansion being adapted to the first coefficient of thermal expansion. The optical element is directly contacting the optical element holder in a wide contact area. The contact area is defined by a first contact surface of the first optical element and a second contact surface of the optical element holder, wherein the second contact surface matches the first contact surface. Thus, favorable rigidity and deformation behavior is provided.
