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
27 Φεβ 2020 · Different microscopic techniques have been developed over the years ranging from optical microscopes to electron microscopes and scanning probe microscopes for the analysis of material morphology on varying length scales.
