Specifications︰Faraday Rotator Glass / Magnetic Optical Glass

Since glass material in high power laser system is damaged as a consequence of self-focusing,low non-linear refractive index as well as high Verdet constant are important factors for Magnetic Optical Glass

Our world-leading MR3-2 and MR4 Magnetic Optical Glass with very high Verdet factor,we supply them with the shape or size of your choice

Very large plates/disks/rods from diameter 1.00 mm to 300 mm are available

MR3-2 and MR4 Faraday Rotator Glass / Magnetic Optical Glass mainly used in faraday rotating components,fabricating optics-isolators,faraday rotators,circulators,magneto-optical modulators,optical switchs,interleavers,laser gyroscopes,goniometric devices magneto-optic storage and optical information process system,current measuring transducers for magnetic field measuring and high-voltage transmission line,new generation current sensors,wave guides, iatrology,spaceflight control,satellite survey and other functional devices

MR3-2 and MR4 Faraday Rotator Glass is made with more advanced technologies,so is performance stabilization,sensitive, and inherently immune to interfere.In comparison with artificial crystal,it is inexpensive and easy to get big size block,it has been made into different types of optical fibers,so it's widely used in many fields
Advantages︰Magneto Optical/Faraday Rotator Elements offer the following advantages

* Diameter: Min.1.00mm-Max. 300 mm
* Highest Verdet constant
* Excellent homogeneity
* Very small stress birefraction
* High damage threshold
* Broad wavelength range
* Better transparency properties
* Lower nonlinear refractive index
* Lower absorption coeffcient
* Lower cost
* Large dimension available
