Metalenses are about 100 times thinner than the thickness of human hair. Unfortunately, the lenses that we currently use in optical instruments like telescopes, microscopes, or cameras can be thicker because they need to divert the light through several bounces before reaching our eyes (or sensors). With Metalenses, this problem is solved once and for all. This blog post discusses with you a few benefits of using Metalenses.
- Metalenses are much thinner than traditional lenses.
Traditional lenses require glass or plastic to divert the light through several bounces before they reach to our eyes. Metalenses are only a fraction of the thickness, making them lighter and easier to transport.
- Metalenses can be made in any shape.
Traditional lenses are round because they are the most straightforward shape to manufacture, and they don’t distort the image. Metalenses can be any shape, allowing for more creativity when designing optical devices. The lens on the left uses a traditional rounded lens, while the one on the right uses metal with an irregular shape.
- Metalenses can be made in a tiny size.
Traditional lenses are bulky, heavy, and expensive to produce. On the other hand, Metalenses can be manufactured with inexpensive materials while maintaining high optical quality at a fraction of the weight and cost.
- Metalenses can be used to correct vision problems.
Traditional lenses use a single prescription for everyone, regardless of their eyesight. However, Metalenses can be designed with different drugs for each individual, correcting vision problems. The lens on the left is a traditional lens, while the lens on the right uses metalenses that have been specifically designed to correct myopia.
The technology has advanced so much in the past century, and with it, our understanding of optics and light. The invention of the Metalens is one more step in improving how we see the world around us.
- Metalenses can be used to create augmented reality devices.
Traditional lenses cannot provide a clear image if the wearer moves around since they need time and space to refocus. On the other hand, Metalenses do not have this problem, allowing for an improved experience in Augmented Reality or Virtual Reality devices.
As you can see, Metalenses have a lot of potential benefits that traditional lenses do not have. They are thinner, lighter, and can be made in any shape or size. Most importantly, they can be used to correct vision problems and create augmented reality devices that provide a better experience for the wearer.
