    摘要: A lithographic projection apparatus contains a projection system for projecting a patterned beam onto a target portion of the substrate. The projection system contains one or more optically active mirrors (20) and heat shields (22,28,29) specifically located for intercepting heat radiation to or from the mirrors and/or their support structure (26). The heat shields are actively cooled and the mirrors and the heat shields and the mirrors are supported separately on a support frame to reduce vibration of the mirrors due to active cooling. The heat shields preferably include heat shields that intercept heat radiation to or from the support structure and/or respective heat shields for individual mirrors that intercept heat radiation to or from the mirrors.

The heat shields are actively cooled and the mirrors and the heat shields and the mirrors are supported separately on a support frame (MF) to reduce vibration of the mirrors due to active cooling. The heat shields preferably include heat shields that intercept heat radiation to or from the support structure and/or respective heat shields for individual mirrors that intercept heat radiation to or from the mirrors.
