    • An assembly for fixation or adjusting of an optical element (1) with, regard to an outer mount or support (4) wherein the optical element (1) is alignable with regard to a structure of the optical arrangement, particularly the objective structure or the objective barrel, having an optical axis or with regard to neighbouring mounts by means of an adjusting arrangement, is characterized in that the adjusting arrangement comprises at least an elastic means (9), particularly a spring, an elastic rod or stick, an elastic tape or an elastic gear wheel or an elastic gear box by which a force or a torque is applicable to the optical element (1). The assembly is particularly suitable for use in a microlithographic exposure apparatus. In some embodiments an intermediate ring (27) positioned between the optical element (24) and the outer mount or support (26) is used to reduce deformations.
    • 一种用于相对于外部安装件或支撑件(4)固定或调节光学元件(1)的组件,其中光学元件(1)可相对于光学装置的结构,特别是物镜结构或 具有光轴或通过调节装置相对于相邻安装件的物镜筒的特征在于,所述调节装置至少包括弹性装置(9),特别是弹簧,弹性杆或杆,弹性带 或弹性齿轮或弹性齿轮箱,通过该弹性齿轮箱,力或转矩适用于光学元件(1)。 该组件特别适用于微光刻曝光设备。 在一些实施例中,位于光学元件(24)和外部安装件或支撑件(26)之间的中间环(27)用于减小变形。
