    • A method of adjusting a projection objective permits the projection objective to be adjusted between an immersion configuration and a dry configuration with few interventions in the system, and therefore to be used optionally as an immersion objective or as a dry objective. The projection objective has a multiplicity of optical elements which are arranged along an optical axis of the projection objective, the optical elements comprising a first group of optical elements following the object plane and a last optical element following the first group, arranged next to the image plane and defining an exit surface of the projection objective which is arranged at a working distance from the image plane. The last optical element is substantially without refracting power and has no curvature or only slight curvature. The method comprises varying the thickness of the last optical element, changing the refractive index of the space between the exit surface and the image plane by introducing or removing an immersion medium, and preferably axial displacement of the last optical element in order to set a suitable working distance.
    • 调整投影物镜的方法允许投影物镜在浸没配置和干燥配置之间进行调节,而在系统中几乎没有干预,因此可任选地用作浸没物镜或干物镜。 投影物镜具有沿着投影物镜的光轴布置的多个光学元件,光学元件包括跟随物平面的第一组光学元件和紧邻第一组的最后一个光学元件,邻近于图像 并且限定投影物镜的离开像面的工作距离处的出射表面。 最后一个光学元件基本上没有屈光力并且没有曲率或仅有轻微的曲率。 该方法包括改变最后一个光学元件的厚度,通过引入或移除浸没介质来改变出射表面和图像平面之间的空间的折射率,优选地最后一个光学元件的轴向位移,以便设定合适的 工作距离

    • The invention relates to a method of making a pump ring for a two-stage vacuum pump (1) with a one-piece rotor system (14) having three sections (14a, b, c), whose end sections (14a and 14c form the two pumping stages and whose middle section (14b) forms an intermediate bearing, the diameters of the bearing section (14band of the rotor section (14a) forming the forepumping stage being equal. To reduce the tolerances that occur it is proposed that two bores be made in a single set-up from one end of a substantially cylindrical workpiece, the one forming the anchor contact (51) of the forepumping stage as well as the bearing bore (12) and the other forming the anchor contact (52) of the high-vacuum stage, and that before or after these bores aremade, additional bores (11, 13) are made in order to form the pump chambers (21, 17).
