Idea is to make an equipment like torch, which should emit darkness.. Is it possible?

Question

Can we have any equipment as such? If light can emit form a hand held device, why not darkness

the closest I have seen is this antilaser experiment http://www.wired.com/2011/02/real-live-antilaser/ — anna v, Jul 07 '14 at 13:16

Darkness is not something. it's the absence of something (photons, Electromagnetics waves)

So if you want to emit the absence of photon. It's kind of hard. Therefor I would say that it's not possible to have such a device.

Now, you can have material that absorb photon.
