Most people who grew up reading the Harry Potter book series have dreamed of owning their very own invisibility cloak.

Now, that dream can become a reality, as scientists have developed an ‘invisibility megashield.’

The £699 shield uses a precision engineered lens array to bend light, rendering objects behind it almost invisibile.

And unlike Harry Potter’s cloak, the megashield is big enough to conceal multiple people standing side by side.

‘Want to experience the power of invisibility? We’ve got you covered,’ said the Invisibility Shield Co.

The megashield is the brainchild of the London-based Invisibility Shield Co, which came up with the initial idea back in 2022.

Since then, the firm has developed and tested various cloaking devices, before landing on the latest design.

The megashield measures 6ft tall and 4ft wide, and is constructed from a high grade polycarbonate.

Using a precision engineered lens array, light reflected from the person standing behind the shield is directed away from the person in front of it.

‘The lenses in this array are oriented so that the vertical strip of light reflected by the standing/crouching subject becomes diffuse when spread out horizontally on passing through the back of the shield,’ the Invisibility Shield Co explained on its Kickstarter page.

‘In contrast, the strip of light reflected from the background is much wider, so when it passes through the back of the shield, far more of it is refracted both across the shield and towards the observer.

‘From the observer’s perspective, this background light is effectively smeared horizontally across the front face of the shield, over the area where the subject would ordinarily be seen.’

According to the team, the shields are most effective against uniform backgrounds, including grass, foliage, sand and sky.

‘Backgrounds with defined horizontal lines work extremely well too and these can be natural features such as the horizon or man made features like walls, rails or painted lines,’ they added.

A previous version of the shield was released in 2022, but was only big enough to fit one person squatting down.

What’s more, users were forced to prop the sheild up themselves.

‘Our new shields have been completely redesigned to be more stable when left free-standing, easy to hold and easy to take wherever you want to go,’ the Invisibility Shield Co said.

‘New ergonomic handles make holding and carrying the shield far more comfortable, whilst keeping your body in the optimum position to stay hidden.’

The company is now crowdfunding on Kickstarter, where you can purchased the Megashield for the early bird price of £699.
