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 μm), all the magnified images are virtual images. When the distance is increased from 0 to 14 μm the magnification decreases from to and the field of view increases from 3.8 to 12.2 μm. The image magnification cannot be described by standard geometrical optics.
