I thinks that just regular polarized light, I believe that cross polarization is different from that.  The filters are twisted to 90 degrees or something like that.

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.

	Is anyone out there familar with cross polarization.  Can it be
	performed on a standard microscope?
	 
	thanks
