摘要	A beam-shaping optical element employing an aspherical profileis presented to minimize aberration. A beam-shaping optical element according to the present invention includes an entrance surface and the exit surface, both having a non-circular cross-section in any plane comprising the optical axis. A beam-shaping optical element according to one embodiment of the present invention, has the optical axis coinciding with the Z-axis of a three-axis rectangular XYZ system of coordinates, and the entrance surface and/or the exit surface represented by a mathematical equation comprising a term representing a non-rotationally symmetric aspherical profile, at least one correction term comprising a function of variable X alone and at least one correction term comprising a function of variable Y alone.
其他摘要	采用非球面轮廓的光束整形光学元件用于最小化像差。根据本发明的光束整形光学元件包括入射表面和出射表面，两者在包括光轴的任何平面中都具有非圆形横截面。根据本发明的一个实施例的光束整形光学元件具有与三轴矩形XYZ坐标系的Z轴一致的光轴，以及由数学表示的入射表面和/或出射表面。该方程包括表示非旋转对称非球面轮廓的项，至少一个校正项包括单独的变量X的函数和至少一个仅包括变量Y的函数的校正项。
