X-RAY DIFFRACTION (XRD). These analytical techniques reveal information about the crystallographic structure, size, chemical composition and physical properties.. Theoretically a microscope is an array of two lenses Need of M icroscopy Living organisms, cells and their organelles which are too small to be seen with the human eye, can only be seen with the aid An electron microscope is a microscope that uses a beam of accelerated electrons as a source o f illumination.
