In this case, the Pockels cell is acting as a quarter wave plate, where linearly-polarized light is converted to circularly-polarized light. With the addition of a Brewster window (left), this change in polarization can be converted to a change in the intensity of the beam, by transmitting only the p-polarized vector component.
Concentration of the sample; Wavelength of light passing through the sample (generally, angle of rotation and wavelength tend to be inversely proportional) Temperature of the sample (generally the two are directly proportional) Length of the sample cell (input by the user into most automatic polarimeters to ensure better accuracy)
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.
Michael Faraday holding a piece of glass of the type he used to demonstrate the effect of magnetism on polarization of light, c. 1857.. By 1845, it was known through the work of Augustin-Jean Fresnel, Étienne-Louis Malus, and others that different materials are able to modify the direction of polarization of light when appropriately oriented, [4] making polarized light a very powerful tool to ...
A phase retarder is an optical element that produces a phase difference between two orthogonal polarization components of a monochromatic polarized beam of light. [3] Mathematically, using kets to represent Jones vectors, this means that the action of a phase retarder is to transform light with polarization
An illustration of the polarization of light that is incident on an interface at Brewster's angle. Brewster's angle (also known as the polarization angle) is an angle of incidence at which light with a particular polarization is perfectly transmitted through a transparent dielectric surface, with no reflection.
The Kerr angle is the angle that linearly polarized light will be rotated after hitting the sample. The Kerr ellipticity ϵ k {\displaystyle \epsilon _{k}} or η k {\displaystyle \eta _{k}} (not to be confused with ellipticity from mathematics) is the ratio of the semimajor and semiminor axes of the elliptically polarized light, generated from ...
An ideal depolarizer would output randomly polarized light whatever its input, but all practical depolarizers produce pseudo-random output polarization. Optical systems are often sensitive to the polarization of light reaching them (for example grating-based spectrometers). Unwanted polarization of the input to such a system may cause errors in ...
