Polarised light micrograph of a thin crystalline film of ferrous sulphate. Ferrous sulphate is used to treat iron deficiency which causes anemia. Anemia is a condition in which the body lacks sufficient red blood cells by having insufficient iron present in the body. The colour is due to both the birefringence exhibited by the ferrous sulphate crystals and the waveplate inserted in the optical train of the microscope. Magnification: x70 when printed at 10cm wide. | |
