• Optical mineralogy — A petrographic microscope, which is an optical microscope fitted with cross polarizing lenses, a conoscopic lens, and compensators (plates of anisotropic materials; gypsum plates and quartz wedges are common), for crystallographic analysis.… …   Wikipedia

• Optical dilatometer — An optical dilatometer is a non contact device able to measure thermal expansions or sintering kinetics of any kind of materials, unlike traditional push rod dilatometer, it can push up to the dilatometric softening of the specimen. It is a… …   Wikipedia

• Optical transfection — is the process of introducing nucleic acids into cells using light. Typically, a laser is focussed to a diffraction limited spot ( 1 µm diameter) using a high numerical aperture microscope objective. The plasma membrane of a cell is then… …   Wikipedia

• Optical sectioning — is the process by which a suitably designed microscope can produce clear images of a focal planes deep within a thick sample. This is used to reduce the need for thin sectioning using instruments such as the microtome. Many different techniques… …   Wikipedia

• Optical dating — is a method of determining how long ago minerals were last exposed to daylight. It is useful to geologists and archaeologists who want to know when such an event occurred. Alternate names sometimes used are optically stimulated luminescence… …   Wikipedia
