Optical microscopy is an imaging methodology with a diffraction-limit given by the wavelength(s) of light used to generate a diffraction pattern and the aperture of the objective lens used to collect the diffracted light source.
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.
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
