Bring examination object into the field of view and turn it through 240° with the mechanical stage.
Birefringent (anisotropic) specimens now normally display the aforesaid color and intensity changes
occurring during rotation between crossed polarizers. However, optically anisotropic substances can
also remain dark if an isotropic direction, e.g. of optically uniaxial or biaxial crystals, is oriented parallel
to the direction of observation.

morphological directions, e.g. of crystal surfaces, crystal needles or fibers, is an important criterion for
recognition. It is also used for the diagnosis of biocrystals (e.g. gout, pseudo-gout).
