What is this witchcraft???[/caption]
If you thought the microcameras in your phone were small, watch out for the newly developed Dual Polarity Plasmonic Metalens. Great, you're saying...well what the heck is that? The Plasmonic lens is an extremely thin lens with a focal length of about 60 micrometers and an aperture of 80mm (roughly the width of a human hair). This is suggesting that the lens would be f/0.75. The addition of gold nano-rod layer on the thin lens allows it to be flat with the properties of both a convex and concave lens. Essentially this means with the flick of a switch the lens can go from wide-angle to telephoto with the aid of a filter. This is all interesting, but will it be practical for photographic purposes? Although some sources are saying this is going to revolutionize camera phone optics, we have to wait and see how this lens compares in terms of sharpness, chromatic aberration, distortion, etc... This leaves me with two questions: Has apple already patented something similar to this and when will they be able to utilize this in equally tiny phones?
