The angle of rotation is given by θ = V l B, where V is the Verdet constant of the glass (given in radians/m·T), l is the length of the glass rod, and B is the magnetic field. The Verdet constant is wavelength dependent and for SF-59 glass is advertised to be 23 rad/m·T for 650 nm light.

Although the Faraday effect is not itself chromatic, the verdet constant itself is quite strongly a function of wavelength. At 632.8 nm, the verdet constant for Faraday  because of its high Verdet constant, V =-4.06 ± 0.1 x 10"Z min/Oe-cm at 1.064 u. This allows one to use ohorte'- lengths of glass and lower magnetic fields than  the Verdet constant. The objectives of this experiment are to measure the Verdet constant for a sample of dense flint glass using Faraday effect and to compare  The Verdet Constant of Light Flint Glass. Thomas G. Spears.

This is in good agreement with the tabulated values of the Verdet con-stant for SF11 Schott glass 10 , from which we interpolate a Verdet constant of 30.44rad T −1m . Each data point in Fig. The objective of this experiment is to measure and analyze the Verdet constant for Corning 7980, a fused quartz glass with no previously published Verdet constant data. This quartz glass is being used at the Belle II experiment at Tsukuba, Japan. The Verdet constant is measured using the Faraday effect — a magneto-optical phenomenon that describes the rotation of the plane of polarization of TGG (Terbium Gallium Garnet) single crystal is currently the best and widely used magneto-optical material in Faraday rotator and isolator due to its extremely high Verdet constants in the range of 400nm-1100nm(excluding 475-500nm). Verdet constant for TGG throughout the visible region.

The Verdet constant is an optical property named after the French physicist Émile Verdet.It describes the strength of the Faraday effect for a particular material. For a constant magnetic field parallel to the path of the light, it can be calculated by: = Where is the angle between the starting and ending polarizations, is the Verdet constant, is the strength of the magnetic flux density, and

The Verdet constant experienced by light in an optical fiber is different from that in bulk glass. In optical fiber, the core and cladding have different Verdet constants, since they are made of different materials. Only a portion of the guided mode exists in The Verdet constant is as large as 0.200 min G −1 cm −1 at 980 nm for 22.5GeS 2 –67.5Sb 2 S 3 –10PbI 2 composition glass, which is the largest value reported thus far for sulfide glasses; this glass also possesses good thermal and optical properties and therefore might be an attractive candidate for mid‐infrared magneto‐optical device applications. Dispersion of Verdet constant and the influence of Tb 3+ concentration on Verdet constant were investigated.

The results show that the rate of change of the Verdet constant at different wavelengths has nothing to do with the Tb3+ concentration, but only with the effective transition wavelength. The effective transition wavelength of the sample was calculated by the formula, and the source of the magneto-optical effect of the rare earth doped magneto-optical glass was confirmed. Another key innovation is glass fiber material itself, a heavily terbium-doped silicate fiber that exhibits a strong magneto-optic: Its Verdet constant is greater than 300 times higher than conventional silica glass. A Verdet constant of 15.18 rad/T/m at 1950 nm with the figure of merit of more than 8.72 rad/T, which is the highest value reported in glass materials at this wavelength, was measured. A Verdet constant of 15.18 rad/T/m at 1950 nm with the figure of merit of more than 8.72 rad/T, which is the highest value reported in glass materials at this wavelength, was measured. Heavily terbium‐doped boron‐silicate glasses (Tb3+10.4 at. %) with a Verdet constant (632.8 nm, room temperature) as large as −0.338 min/Oe cm, 38% larger than that of the famous FR‐5 glasses, have tionality constant and is called a Verdet constant.
