Advanced Materials Characterization Chapter 7 - by Igor Bello

Optical microscopy (OM) has been used to observe small objects and their features on the scale of micrometers and sub-micrometers in diverse fields of engineering, metallurgy, electronics, biology, medical science, etc. Although OM has been known for hundreds of years, it has been developed to sophisticated methods of analyses especially over recent years along the advancement of digital electronics.

Optical microscope, as an analytical tool, is applied not only to acquire simple optical images, but also to reveal the grain sizes of materials, interface boundaries, and cavities, nature of crystals, crystallographic orientation, to measure crystal length, angles, and faceted areas, and to determine optical properties of materials such as refractive index, reflectance, and phase changes, etc. OM aided with digital video recording can image very thin optical sections. Optical confocal microscope systems are already used by many research institutions. OM is an absolutely crucial method in the forensic, biological, and medical fields. Optical microscopy is used to identify and study bacteria and viruses, and it is used in diagnosing diseases.
