微型镜片多用作近视镜片。对微尺度球面透镜的远场成像特性进行了实验研究。我们的实验结果表明，对于间距为300 nm的蓝光光盘(物体)，当透镜与物体在空间上分开时，透镜可以放大光盘的条纹图案。在实验测试的范围内(0-14微米)，所有放大的图像都是虚拟图像。当距离从0增加到14微米时，放大倍数从1.47倍下降到1.20倍，视场从3.8微米增加到12.2微米，这是标准几何光学无法描述的。(C)2013年美国光学学会
Microscale lenses are mostly used as near-sighted lenses. The far-field imaging properties of a microscale spherical lens, where the lens is spatially separated from the object, are experimentally studied. Our experimental results show that, for a blu-ray disc (an object) whose spacing is 300 nm, the lens can magnify the stripe patterns of the disc when the lens is spatially separated from the object. In the experimentally tested range (0-14 mu m), all the magnified images are virtual images. When the distance is increased from 0 to 14 mu m the magnification decreases from 1.47x to 1.20x and the field of view increases from 3.8 to 12.2 mu m. The image magnification cannot be described by standard geometrical optics. (C) 2013 Optical Society of America
