Stargate SG-1, Season 6

Maj. Carter:
Well, whoever it is, we're dealing with an enemy we can't see. Without TERs to counter that technology, we're helpless.

Malek:
Do you have the means to generate a high-frequency electromagnetic field?

Maj. Carter:
I could modify the wave output of the naquadah reactor.

Malek:
Within a range of 400 to 700 nanometers?

Maj. Carter:
That might just excite the phase particles enough to bring them into our visible light spectrum.

Col. O'Neill:
Carter?

Maj. Carter:
Sir, the invisibility field must operate-

Col. O'Neill:
Are you about to tell me that you can make the invisible guy vi-

Maj. Carter:
Yes, sir.

Col. O'Neill:
That's all I need.

Jacob Carter:
If you can see it, you can shoot it.
