Principal section of crystal
WebA crystal is placed in a polariscope, the polarizer and analyzer being parallel. The principal section of the crystal makes an angle of 35degree with the planes of transmission of the polarizer and analyzer. Find the ratio of the intensities of the E and O beams (a) as they leave the crystal and (b) after they leave the analyzer. Ans. WebPrincipal Section. If the mineral grain is oriented such that the optic axis is oriented parallel to the microscope stage, then we can imagine the principal section of the indicatrix as being parallel to the top of the grain such as would be the case for a crystal lying on face c in the diagram above.
