| polarised light | Light in which, as a result of reflection or transmission through certain media, the vibrations are all in one plane, transverse to the ray, instead of in all planes. (05 Mar 2000) |

| polarising microscope | <instrument> A microscope equipped with a polarising filter below and above the specimen which forms an image by the influence of specimen birefringence on polarised light; the polarising direction of the two filters is typically adjustable which, together with a graduated rotating stage, permits measurement of the angular value of different refractive indices in either biological or chemical specimens.
