The Harry Potter invisibility cloak is one step closer to reality

Scientists at the University of Rochester have developed a new lens which will allow objects to become 'invisible'.

Unlike other cloaking devises, it can work in 3D. As research published in Optics Express detail, the device is made by four ordinary lenses and can make objects look like they are invisible when viewed in a number of different angles.

"This is the first device that we know of that can do three-dimensional, continuously multidirectional cloaking, which works for transmitting rays in the visible spectrum," said Joseph Choi, the paper's lead author. "This cloak bends light and sends it through the center of the device."

The good news is that in can be scaled up - meaning that the dream of creating an invisibility cloak, like the one JK Rowling describes in Harry Potter is one step closer to reality.
