An EM emitter was a hand-held device used for the focused projection of electromagnetic radiation. They were used by Starfleet in the 22nd century.

In 2152, when several members of the Enterprise NX-01 crew were captured by an unknown lifeform, Malcolm Reed and a security team attempted to use EM emitters to weaken the creature, as Doctor Phlox had determined that the creature was highly photosensitive. (ENT: "Vox Sola")

In 2153, Commander Tucker considered using portable EM emitters to fire sustained bursts of delta radiation at Xindi-Reptilian weapons in order to disable them, but Phlox informed him that the amount of delta radiation necessary to do that would also be extremely hazardous to humanoid life.
