#THOR LABS FARADAY ISOLATOR SERIES#
Thorlabs-science-desks-and-faraday-cages-3-digitimerScienceDesks are supplied complete with our best, Nexus series breadboard and are compatible with 2′ (600 mm) deep lab furniture.Īn extensive range of accessories is also available These corner option desks are available with either active or heavy duty passive isolation or rigid non-isolating supports. The upper and lower rails on the ScienceDesk frame allow the user to strategically place shelves and other accessories around an imaging system so that supporting equipment can be in close proximity to the isolated surface without being on it.Ī corner option is also available that fits in the corner of the lab/room and permits access to the entire breadboard surface from the slanted corner.
We offer stainless steel tabletops with or without a regularly spaced mounting holes. The tabletop is also protected from incidental contact because it rests inside the frame’s outer rails. ^ "Optical Isolator Tutorial ( of 2)" (PDF).

In this way, the device can be tuned for use with a range of lasers within the design range of the device. Many Faraday rotators and isolators are adjustable by varying the degree to which the amount of the Faraday rotator material is inserted into the magnetic field of the device. This behavior means that the devices manufactured with a certain degree of rotation at one wavelength, will produce much less rotation at longer wavelengths. m), whereas at 1064 nm it falls to −38 rad/(T. At 632 nm, the Verdet constant for TGG is reported to be −131 rad/(T it depends on wavelength) and therefore the Verdet constant is quite a strong function of wavelength. The highest Verdet constants are found in terbium doped dense flint glasses or in crystals of TGG. The Verdet constant increases substantially as the mineral approaches cryogenic temperatures. TGG has a high Verdet constant which results in the Faraday effect. TGG can be used in optical isolators for laser systems, in optical circulators for fiber optic systems, in optical modulators, and in current and magnetic field sensors. This is a Faraday rotator material with excellent transparency properties and is very resistant to laser damage. Terbium gallium garnet ( TGG) is a kind of synthetic garnet, with the chemical composition Tb 3 Ga 5 O 12.
