A new interpretation of the optical interference figures observed in a A conoscopic interference pattern or interference figure is a pattern of birefringent colours crossed by dark bands (or isogyres ), which can be produced using a geological petrographic microscope for the purposes of mineral identification and investigation of mineral optical and chemical properties. Lecture Notes - Optics 7: Biaxial Minerals The interference figure obtained for a biaxial mineral depends on the orientation of the mineral with respect to the microscope stage. Light waves passing through crystals can have a variety of wavelengths, amplitudes, and phases affected by atomic structure in different ways. As a result, the biaxial interference image can be seen when the mica flake is lying flat on the microscope slide.
