10.12.3 Centering the Objectives of the Polarization Stand
Stage centering is necessary to ensure that a sample feature located in the center of the field of
view does not move out while you are rotating the stage. Centering all objectives ensures that the
sample feature remains in the center of the field of view even when the objective is changed.
