Whether you’re an iPhone person, Huawei super-fan, Samsung phone devotee or OnePlus worshipper, everybody can agree that camera bumps – protrusions in a phone’s casing, the place the camera is housed – are annoying. They get broken simply, cease you mendacity your phone flat on a desk, and really feel irritating once you’re holding your phone in panorama. However, an answer is in hand.

This answer comes from the University of Utah, in Salt Lake City, the place a bunch of researchers have simply invented smartphone camera lenses which can be only a few micrometers thick. If you don’t know what a micrometer is, perhaps this provides you with an concept: it’s a millionth of a meter, which means these lenses are hundreds of occasions thinner than these presently in use in flagship smartphones – and twenty occasions thinner than a human hair.

This information was revealed in a scientific paper titled “Broadband lightweight flat lenses for long-wave infrared imaging”, which describes a very tiny optical lens. It can fulfill all of the capabilities of a thicker smartphone lens by successfully creating quite a few tiny buildings that bounce mild to the sensor, working collectively to act as a lens.

A super-thin smartphone lens sounds nice, however how will this truly rework your camera expertise? We spoke to Rajesh Menon, {an electrical} and pc engineering affiliate professor on the University of Utah, to higher perceive these little lenses.

Understanding super-thin smartphone lenses

The University of Utah researchers’ prototype lens was flat, however most smartphone lenses are rounded – the ‘main’ camera on a phone is often a wide-angle lens. Naturally, then, our first query was about lenses. 

Specifically, we requested Menon if these micrometer lenses would come in numerous specs – corresponding to ultra-wide angle, telephoto, macro, or extra. The reply was easy sufficient: “Yes, that is precisely what we do.”

“The concept is to make this utterly clear to a lens designer. In different phrases, the lens designer will specify [what they want] and our algorithms will flip these specs into flat lens designs.” So it’s very potential that these lenses will are available in all of the configurations you see on the again of your smartphone already.

The tech is nice, however as is usually the case with scientific breakthroughs like this, it’s potential that it could nonetheless be a methods off arriving in retail – so our subsequent query was whether or not we could see this in smartphones any time quickly, and what sort of time scale this could be. 

“My best guess is 2-Three years,” Menon informed us, including that, “Before smartphones, there are applications in aerospace and UAVs, where these lenses will be applied.” 

When information of the analysis broke, a number of different makes use of for the lenses had been touted alongside smartphones, corresponding to lighter army drones, or evening imaginative and prescient gear, primarily for army use – and it’s potential the lenses will be deployed for these functions earlier than making their manner to smartphones.

It’s very simple to drop a smartphone and have it break, and this threat is elevated considerably if the lens in use is a twentieth the thickness of a human hair, so our closing query was about the frailty of this lens. According to Menon, although, there’s nothing to fear about: “All lenses today are protected behind strong glass, so this can be the same for our lenses as well.” 

In quick, you’d have to severely injury your phone for the lenses to be affected.
