All still lenses have a certain amount of breathing, but to varying degrees—some of which can be very distracting to watch. If this presents a problem in post production, the image can be digitally zoomed to counteract the zoom effect of the breathing.

Web27 sep. 2006 · We present a radial gradient-index (GRIN) lens with an index-of-refraction ranging from -2.67(edge) to -0.97(center). Experimentally, we find the lens can produce field intensities at the focus that are greater than that of the incident plane wave. These results are obtained at 10.45 GHz and in excellent agreement with full-wave simulations. WebLenses such as convex and concave lenses are widely used for beam forming, focusing, imaging, etc. For example, glass lenses are widely adopted in terahertz and optical circuits, and dielectric lenses are used to generate directive beams in microwave antennas.
