我们提出了一种低成本制造非球面变形透镜的新方法。将可紫外光固化的负极光刻胶液滴置于不对称基板上，当其表面形状在静电力作用下演变为非球面并满足设计的最佳形状时进行固化。数值分析和实验结果表明，所制备的透镜在两个横向方向上具有不同的光功率，可以在快轴方向上对激光二极管产生的发散光束进行高能量准直。(C) 2013 Elsevier B.V.版权所有
We propose a novel method to fabricate aspherical anamorphic lenses at very low costs. A droplet made of UV-curable negative photoresist is placed on an asymmetrical substrate and cured when its surface shape evolves to be aspherical due to electrostatic force and meets the designed optimal shape. Both numerical analysis and experimental results are presented, showing that the fabricated lens has different optical powers in the two transverse directions and can collimate the divergent beam generated by a laser diode in the fast-axis direction with high energy efficiency.
