Equip the lens for mobile phones and tablets

In the near future, the camera on the mobile phone will also be fitted with small lenses that allow you to change between extreme angles of photography to magnifying mode for viewing in just one simple operation.

Specifically, scientists have developed an ultra-thin lens that can act as a convex lens or a concave lens with just a gentle shift. That means the scene can be magnified or viewed in wide angle. This allows for a new generation of lenses for cell phones and tablets that allow photographers to take beautiful pictures that they previously wanted to have. expensive (single lens reflex camera).

The scientists created these lenses, known as super-plasmonics, by depositing the nano-barbed layers into a flat lens half the width of human hair. According to Dr Shuang Zhang, associate professor of meteorology at the University of Birmingham, who led the research, the device has great flexibility in designing and adding new functions to the optical system. learn. The focus adjustment feature can switch between the convex and concave lens as you like. Moreover, the compact size and flatness of the lens is very convenient.
