Samsung Electro-Mechanics told about the development of a metallens or superlens: it is a flat structure with
Fundamentally similar to the so-called Fresnel lenses, the new developments make it possible toto create high-quality nanometer-thick optics.
According to Samsung, the technology will allow the production ofthinner and lighter smartphone cameras than those currently used by manufacturers. When Samsung's metal lenses go into mass production, they will eliminate the typical disadvantage of smartphones - the protrusions of the camera module above the rear surface, which are typical even for expensive models.
The company is now testing the new technology in its own production.developments in this direction.
According to the company, the superlenses are mass-produced using semiconductor chip technology.They have a micronanostructure of the surface to modulate the phase of incident light.molding process used in traditional lens manufacturing.
This allows for a significant increase in productivity, which in turn reduces the cost of the finished product. Superlens thickness ranges from hundreds of nanometers to
