非球面透镜结构的制造方法
摘要：
一种非球面透镜结构的制造方法，包括：提供一基板；在该基板上形成一通孔，用可光分解的树脂制成一球面透镜；向该通孔中插入该球面透镜，并露出该球面透镜的一预留曲面；向该基板上涂布一黑色染料层，并挡住该球面透镜的部分区域；在该基板上顺应性地形成一光阻层，覆盖该球面透镜；对该光阻层进行灰阶微影加工，以通过该光阻层在该球面透镜上形成具有一非球面顶表面的一第一透镜构件；利用紫外光照射该球面透镜，照射后的该球面透镜由化学溶剂溶解，留下一空穴；以及在该空穴中形成具有一非球面背表面的一第二透镜构件。
摘要（英）：

The invention provides an aspheric lens structures and fabrication methods thereof. The aspheric lens structure includes a first lens component with an aspheric top surface disposed on a second lens component, wherein the interface between the first lens component and the second lens component is spherical. The second lens component includes an aspheric back surface, wherein the radius of curvature of the aspheric top surface of the first lens component is different than the radius of curvature of the aspheric back surface of the second lens component. The second lens component may also include a planar back surface with a third lens component disposed on the planar back surface of the second component. The third lens component includes an aspheric back surface, wherein the radius of curvature of the aspheric top surface of the first lens component is different than the radius of curvature of the aspheric back surface of the third lens component.
