Applications of Optical Microscopy 1. Crystal morphology and symmetry • Crystal fragments (characteristic shape) • Classify isotropic and anisotropic substances • Check possible symmetry (parallel extinction) 2. Phase identification, purity and homogeneity • Standard optical data (refractive indices and optical axes) for comparison
Phase-contrast microscopy. Phase contrast is an optical contrast technique for making unstained transparent objects visible under the optical microscope. An annulus aperture is placed in the front focal plane of the condenser and limits the angle of the penetrating light waves.

In optical microscopy, light is used to probe a sample. To do this with maximum efficiency, causing minimum damage to the sample itself, suitable imaging config-urations are exploited to get maximum signal-to-noise ratio (S/N). All these meth-ods are named contrast techniques and are the subject of this section. 1.2.1 Ray Optics
The laboratory work described in this paper represents a practical means of providing students experience with basic optical microscopy techniques that are widely used in industry but largely absent from the undergraduate chemistry curriculum.
