Smartphones today are quickly advancing in terms of display, processor, battery, and imaging. The camera system is still the same although some advancements are already being made. It used to be the higher megapixels, the better but we learned that it’s not really the solution. It’s mainly the type of lens that matters. OEMs have started to change the lens they use or are looking for the best technology. We’ve seen improvements in imaging, thanks to the likes of the dual camera systems and even the Leica lens on Huawei phones.
Scientists have recently discovered that flat lens could be a game changer. It’s not any ordinary flat lens but ultra-thin ones. Curved lenses are usually used but they have flaws, compromising the sharpness of an image. The flat lens will reduce the problem and is said to revolutionize optics. This is according to the scientists and investors who worked on the technology.
The flat lens is really thinner at 2mm but it can magnify objects for a sharper focus. It’s much like a microscope lens but a lot more powerful. It’s made possible by the metamaterials and so the lens is called this early as ‘metalens’. It is described as lighter and smaller so it can be a game-changer in the mobile imaging tech.
The ‘metalens’ is described as a very thin layer of transparent quartz that has been coated in millions of tiny pillars that interact with light. Metalens avoid aberrations that are common in glass optics. The researches even compared the lenses with the other premium ones used microscopes for scientific purposes and researches. They are more compact now so don’t be surprised if you find them on future smartphones.
