Optical Illusions definition: An illusion of vision usually affecting spatial relations.
Optical Rotation definition: The rotation of linearly polarized light as it passes through various media.
optical rotation definition: rotation of the plane of polarization in a beam of light as it passes through an optically active substance; may be clockwise or counterclockwise.
optics definition: science that deals with the genesis and propagation of light, the changes that it undergoes and produces, and other phenomena closely associated with it.
Optics definition: The branch of physics that describes the behavior and properties of light and the interaction of light with matter.
Unit of Optical Density definition: An indication of the type of unit of measure being used to express an optical density of a substance.
LIGHT, MICROSCOPE definition: Microscopes and accessories are optical instruments used to enlarge images of specimens, preparations, and cultures for medical purposes. Variations of microscopes and accessories (through a change in the light source) used for medical purposes include the following: (1) Phase contrast microscopes, which permit visualization of unstained preparations by altering the phase relationship of light that passes around the object and through the object. (2) Fluorescense microscopes, which permit examination of specimens stained with fluorochromes that fluoresce under ultraviolet light. (3) Inverted stage microscopes, which permit examination of tissue cultures or other biological specimens contained in bottles or tubes with the light source mounted above the specimen.
light microscope definition: A microscope (device to magnify small objects) in which objects are lit directly by white light.
Microscopes, Light definition: Microscopes in which the specimen is viewed by being placed in a light path (which may be white light composed of all visible wavelengths, ultraviolet light, or, less frequently, infrared light). These microscopes include a stand, eyepieces, objectives, condensers, and illumination systems.
optical communication definition: any form of communication that utilizes light to transmit or receive signals representing speech, pictures, or other information; includes things such as smoke signaling, heliography, distress flares, and the data transmission via fiber optics, however see also FIBER OPTICS.
