De·po·lar·ize v. t. [imp. & p. p. Depolarized p. pr. & vb. n. Depolarizing.]
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.
