Depolarize

Depolarize \De*po"lar*ize\, v. t. [imp. & p. p. Depolarized; p. pr. & vb. n. Depolarizing.] [Pref. de- + polarize: cf. F. d['e]polarizer.]

  1. (Opt.) To deprive of polarity; to reduce to an unpolarized condition.

    Note: This word has been inaccurately applied in optics to describe the effect of a polarizing medium, as a crystalline plate, in causing the reappearance of a ray, in consequence of a change in its plane of polarization, which previously to the change was intercepted by the analyzer.

  2. (Elec.) To free from polarization, as the negative plate of the voltaic battery.
