Other methods for observing spherulites

Spherulites can also be observed by means of electron microscopy, electron diffraction and X-ray diffraction. These are methods for observing a single spherulite or a few spherulites in detail, as is the optical-microscope method, whereas light scattering, as pointed out above, gives only an average size for many spherulites in the sample. 

After the growth of these primary lamellar stacks, which do not occupy the whole of the volume within the boundary of the spherulite, growth of secondary stacks occurs. These usually consist of material of lower molar mass that had been excluded from the primary growth.
