1. A method for inhibiting condensation distortion on an optical element, the method comprising:
detecting the optical element inserted into a plasma-activation region within a housing, wherein the plasma-activation region is configured to contain gas on a first side of a dielectric barrier;
electrically connecting a first electrode located on the first side of the dielectric barrier with a second electrode located on a second side of the dielectric barrier, opposite the plasma-activation region;
applying an electric field associated with a potential drop of greater than 1000 V between the first electrode and the second electrode to thereby generate plasma within the plasma-activation region; and
maintaining the generated plasma in the plasma-activation region for time period sufficient to cause the optical element to become hydrophilic.
