光学投影系统
摘要：
一种光学投影单元，包括第一光学元件模块和至少一个第二光学元件模块。第一光学元件模块包括第一外壳单元和至少第一光学元件，第一光学元件容纳在所述第一外壳单元内并具有限定第一光轴的光学用途第一区域。至少一个第二光学元件模块位于所述第一光学元件模块附近，并包括至少一个第二光学元件，所述第二光学元件限定光学投影单元的第二光轴。第一外壳单元具有中央第一外壳轴线以及围绕着所述第一外壳轴线沿着圆周方向延伸的外壁。第一光轴相对于所述第一外壳轴线横向偏置和/或倾斜。另外，第一外壳轴线与第二光轴基本上共线。
摘要（英）：

An optical projection unit comprising a first optical element module and at least one second optical element module is provided. The first optical element module comprises a first housing unit and at least a first optical element, the first optical element being received within the first housing unit and having an optically used first region defining a first optical axis. The at least one second optical element module is located adjacent to the first optical element module and comprises at least one second optical element, the second optical element defining a second optical axis of the optical projection unit. The first housing unit has a central first housing axis and an outer wall extending in a circumferential direction about the first housing axis. The first optical axis is at least one of laterally offset and inclined with respect to the first housing axis. Furthermore, the first housing axis is substantially collinear with the second optical axis.
