LG Metalenses promise ultra-compact phones with perhaps flush-mounted cameras

Tech Highlights:

  • The metalens is basically an ultrathin planar structure with nanoparticles scattered on it, which have the ability to shape-shift and focus light like regular lenses, but with the important caveat that the whole set can be made up to one micron thin. LG says that together with academic research institutions it is developing a microlens that is 1/10,000th of the regular lens thickness and can find application anywhere where micro-cameras are needed.

According to Korean media The Elec, LG is developing an innovative ultrathin lens technology that it claims may be used for phone cameras as well. They are called metalenses, and they replace the current phones’ cumbersome glass or plastic lenses that make up the majority of the camera islands that protrude from our smartphones.

LG Innotek’s CEO added that the company is trying “to implement an ultra-thin lens by replacing the refractive lens with a planar meta surface. To this end, the development of the preform (free form) meta surface unit structure and the optimal design of the unit structure arrangement must be carried out.” Current phone camera lenses, especially ones that have huge sensors underneath like those on the new Xiaomi 12s Ultra, have the tendency to stick out like sore thumbs. Even liquid lenses with variable focus are simply a pouch with liquid inside and still huge compared to the metalens promise.

With $1000 off for an S21 Ultra trade-in, even one with a cracked screen, and $100 of Samsung credit towards accessories, the S22 Ultra can be had for up to $1100 off. If you are upgrading from a Note 20 Ultra then you can get $825 for your broken oldie, plus 30% off the Galaxy Tab S8 in a bundle with Samsung’s finest from the S-line, too.

If LG manages to commercialize its metalens research, we will be in for much thinner phone cameras that might be flush with the rear surface for a change and shave off the ever-increasing weight of our giant handsets.

The LG Innotek CTO presenting their metalens development Samsung confirmed that it is also working on metalenses, so there could soon be veritable competition in the field, which can only benefit us mortal users.
