摘要： A system and method for fixing a projection lens 102 and adjusting the position of a projection lens 102 is provided, which is compact and has a high precision. The projection lens 102 is positioned on a base plate 104. The position of the projection lens can be adjusted by providing possibilities for horizontal and vertical shift in a plane perpendicular to the optical axis of the projection lens 102. This is performed by actuating three points of the base plate 104. Furthermore, by providing further shifting means at the three points of the base plate 104, tilting of the projection lens can be performed, thus providing Scheimpflug correction. In this way, motion of the projection lens in five degrees of freedom is provided by actuating three points at a base plate 104 whereon a projection lens 102 can be easily mounted and removed.
摘要翻译：提供一种用于固定投影透镜102并调整投影透镜102的位置的系统和方法，该系统和方法是紧凑的并且具有高精度。投影透镜102位于基板104上。可以通过提供垂直于投影透镜102的光轴的平面中的水平和垂直移动的可能性来调整投影透镜的位置。这通过致动基板104的三个点来执行。此外，通过在基板104的三个点处提供进一步的移位装置，可以执行投影透镜的倾斜，从而提供Scheimpflug校正。以这种方式，投影透镜在五个自由度上的运动是通过在基板104处致动三个点而提供的，其中投影透镜102可以容易地安装和移除。

摘要： A convergence system 100 comprises a dichroic prism 102 for splitting and/or recombining light beams, intermediate parts 104a, 104b, 104c and a light modulator 106a, 106b, 106c for every color beam. The intermediate parts 104a, 104b, 104c are constructed such that the convergence system has an improved resistance for variations in environmental effects like temperature and humidity. The intermediate parts 104a, 104b, 104c are constructed such that the convergence system has a high stability, a large degree of monolithicy and a high movement isotropy. When used in a projection display system, the projection display system has a high degree of color uniformity.
