| depolarise | 1. <optics> To deprive of polarity; to reduce to an unpolarised condition. This word has been inaccurately applied in optics to describe the effect of a polarising medium, as a crystalline plate, in causing the reappearance of a ray, in consequence of a change in its plane of polarisation, which previously to the change was intercepted by the analyser. 2. <physics> To free from polarisation, as the negative plate of the voltaic battery. Origin: F. Depolariser. Source: Websters Dictionary (01 Mar 1998) |
