Observations in convergent light

If we examine the sections of an-isotropic minerals under a convergent polarized light, the ”interference figures” can be seen. In order to observe these figures, we need to make some pre-adjustments in the polarizing microscope. Polars are crossed. Condenser lens is used below the stage to produce a converging beam. A high power objective is …
