Abstract
A method for producing a mirror of a microlithographic projection exposure apparatus comprises providing a first mirror part having a first connecting surface and a second mirror part having a second connecting surface is provided. Cooling channels and/or auxiliary channels are formed in the second mirror part. The method also includes bringing together the first and second mirror parts so that initially a partial region of the first connecting surface and a partial region of the second connecting surface come into contact and form a common contact surface. The method further includes enlarging the contact surface by continuing to bring the first and second mirror parts together in a transverse direction with respect to the cooling channels or auxiliary channels.
