De*po"lar*ize (?), v. t. [imp.
& p. p. Depolarized (?); p. pr. & vb.
n. Depolarizing.] [Pref. de- +
polarize: cf. F. dépolarizer.]
1. (Opt.) To deprive of polarity; to
reduce to an unpolarized condition.
&fist; 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.
