The Physics Of An “Invisibility Shield”, Real Invisibility Shield

In this video I explore the physics of an ‘invisibility shield’, otherwise known as a Lubor’s Lens.You may have seen viral clips of this type of material attached to a riot shield, advertised for police and military applications to provide an effective (but not perfect) cloak in certain environments. This video explores how that technology works.

Popularised by Paul Harris and invented by Lubor Fiedler, the Lubor Lens is a fantastic optical illusion. Lubor’s Lens is an amazing prop that allows for extremely magical moments, if handled correctly.

The light goes in and is dispersed by the lens, then splits when it hits the object behind the screen. Watch the video above from NightHawkInLight for more info.


It fits in a wallet, can be used with a variety of items and creates effects not possible with any other method. The material boasts “broadband invisibility,” which means it can render a subject invisible from a variety of spectrums.
