We present a novel, to the best of our knowledge, fabrication process for highly aspherical lenses based on surface deformation due to thermal expansion of a soft polymer, polydimethylsiloxane (PDMS), using laser-structuring, molding, and precise shape optimization. Our fabrication process can be used for almost any lens shape with a large degree of freedom—both individual lenses and dense arrays. We present the design, fabrication, and characterization with examples of four different lenses with 1 mm apertures and surface deviations below 100 nm.

小型非球面镜片的制造工艺

据我们所知，我们提出了一种新的高度非球面镜片的制造工艺，该工艺基于由于激光聚合物，聚二甲基硅氧烷（PDMS）的热膨胀而产生的表面变形，并使用激光结构化，模制和精确的形状优化。我们的制造工艺几乎可以用于任何具有很大自由度的镜片形状-单个镜片和密集阵列。我们以孔径为1 mm且表面偏差低于100 nm的四种不同透镜为例介绍设计，制造和表征。
