Light Interference Figure Pattern Stock Image A200 0184 Science One easy way is to take a moderately thick but still clear sheet of mica, sandwich it between two crossed polarizers, then look at a blank white wall or the sky. the interference figure is easily seen. this is a biaxial figure the mineral has two optic axes. This document discusses interference colors and interference figures seen in anisotropic minerals under polarized light microscopy. it describes how interference colors are produced when minerals are rotated to their extinction positions. The figure to the right shows interference between two spherical waves. the wavelength increases from top to bottom, and the distance between the sources increases from left to right. Quartz in pp light quartz in xp light off center uniaxial interference figure of quartz positive uniaxial interference figure of quartz epidote epidote in pp light epidote in xp light off center biaxial optic axis figure of epidote negative biaxial optic axis figure of epidote topaz topaz in pp light topaz in xp light off center optic axis.

Interference figures are obtained when the microscope is used in its conoscopic configuration. this means that light is made to pass through the specimen in as wide a range of directions as possible. The "maximum" (highest order) interference colors are diagnostic for a given mineral. in the chart above, the colors under the mineral names are typical interfence colors for the given mineral. This document discusses how to obtain and interpret interference figures under crossed polars for uniaxial and biaxial minerals. 2. key steps to obtain an interference figure are centering the grain, focusing, inserting condenser and bertrand lenses. 3. wave interference.
