Yes, it can be done. You just need two polarizing filters, one to be placed at the exit of the light source (before the light enters the microscope condenser) and the second over the slide (or inside one ocular).
You will make the field dark by crossing the two filters and later you place the object and will determine if there was a change in the field characteristics.
