Scientists from Stanford and the University of Amsterdam have achieved a breakthrough in lens technology by creating the world’s thinnest lens, measuring just three atoms thick. This innovative development has opened up new possibilities for applications in various fields.
Lenses are typically made of curved glass or other transparent materials to collect, bend, and focus light towards a specified point. These lenses can correct our vision, magnify objects through microscopes, or allow us to see distant objects through telescopes. However, traditional lenses can be quite thick and heavy, especially when made of glass. This is why an alternative design called a Fresnel lens was invented in the 19th century. These lenses use concentric circles of material to diffract light, resulting in thinner lenses.
The newly developed lens is only 0.6 nanometers thick and consists of concentric rings of tungsten disulphide. It selectively focuses red light while allowing other wavelengths to pass through unaffected. This unique feature opens up potential applications such as wearable glasses for augmented reality. The researchers are now exploring if the technique can be used to create more complex coatings activated by small electrical zaps.
This groundbreaking research was published in Nano Letters, showcasing the potential for future advancements in lens technology. With the creation of the world’s thinnest lens, new possibilities for applications in various fields are on the horizon.
In conclusion, this revolutionary development has opened up new avenues for future advancements in lens technology that could have significant implications across different industries such as healthcare, optics and electronics among others.
In summary: Scientists from Stanford and the University of Amsterdam have created the world’s thinnest lens that measures just three atoms thick using concentric rings of tungsten disulphide which selectively focuses red light while allowing other wavelengths to pass through unaffected.
