. Elementary chemical microscopy . Fig. 22. Construction and Path of Light Rays in a Nicol Prism. 1 In the newer polarizing microscopes, the prisms often do not have a rhombic cross-section and therefore their planes of vibration do not fall in the direction of a short diagonal. The position of the planes of vibration must then be ascertained experimentally; see Weinschenk, Das polarizations Mikroskop.
