Optical rotation, also known as polarization rotation or circular birefringence, is the rotation of the orientation of the plane of polarization about the optical axis of linearly polarized light as it travels through certain materials. Circular birefringence and circular dichroism are the manifestations of optical activity. … See more Dextrorotation and laevorotation (also spelled levorotation) are terms used in chemistry and physics to describe the optical rotation of plane-polarized light. From the point of view of the observer, dextrorotation refers … See more Optical activity occurs due to molecules dissolved in a fluid or due to the fluid itself only if the molecules are one of two (or more) stereoisomers; this is known as an enantiomer. … See more Rotation of light's plane of polarization may also occur through the Faraday effect which involves a static magnetic field. However, this is a distinct phenomenon that is not classified … See more • Eugene Hecht, Optics, 3rd Ed., Addison-Wesley, 1998, ISBN 0-201-30425-2 • Akhlesh Lakhtakia, Beltrami Fields in Chiral Media, World Scientific, … See more The rotation of the orientation of linearly polarized light was first observed in 1811 in quartz by French physicist François Arago.

WebOrienting Dichroic Beamsplitters and Other Unhoused Optical Filters. Dichroic beamsplitters and other unhoused optical filters feature orientation marks that identify the coated surface upon which light must be incident. An orientation mark is placed either on the front surface of the filter, or on the edge of the filter as a caret (^) mark. WebNov 1, 2008 · Optical detection is now the preferred method to detect spin alignment in semiconductors. The orientation of spins in crystals pumped with circularly polarized light … WebOne of the most frequently used and powerful methods of generation and investigation of spin polarization is optical orientation [ 1 ]. Besides purely optical phenomena like circularly-polarized photoluminescence, the optical generation of an unbalanced spin distribution in a semiconductor may lead to spin photocurrents.
