论文摘要
在他们的文章-Appl中。选择。 58,1010_1015(2019)-González-Acuña等人声称:“一种用于设计自由形镜片的分析闭合形式公式,没有球形像差和散光。”但是,正如我们在此处显示的那样,只有当对象和图像都是真实的,并且图像被反转时,才能应用它们的公式,此外,对象中的折射索引和图像介质是相同的。在这里,我们提供了此特定公式的完整解决方案。
In their article -Appl. Opt. 58, 1010_1015 (2019)- González-Acuña et al claimed:"an analytical closed-form formula for the design of freeform lenses free of spherical aberration and astigmatism." However, as we show here, their formula can only be applied when the object and image are both real and the image is inversed, additionally, the refractive index in the object and image media is the same. Here, we present the complete solution of this particular formula.
