Xi'an Aofa Optoelectronics Tech Inc. (XAOT) is leading manufacturer specialized in R&D a series of rare-earth doped glass material / faraday rotator glass material with high Verdet constant and special photonics properties in shapes of rod, disk and slat to meet the needs of various laser applications.

Owning sole intellectual property and Know-How of Faraday Rotator Glass material on melting, casting, fine-annealing and all that, they have very high Verdet constant, damage threshold, transparency properties as well as excellent homogeneity, extinction ratio and wide wavelength range with lower nonlinear refractive index than all other glass alike.

* Paramagnetism Faraday Rotator Glass Material:

Type MR3-2, Verdet constant -0.3 min/OE-cm at 632.8nm or -96 rad /T*m at 632.8 nm

Type MR4, Verdet constant -0.38 min/OE-cm at 632.8nm or -110 rad /T*m at 632.8 nm

* Diamagnetic Faraday Rotators Glass Material:

Type MR1, Verdet constant +0.070-0.085 min/OE-cm at 632.8nm, used especially for MOCT.

The glass materials and their optics are high sensitive and steady widely used in high-power optical rotator and isolator with large aperture, circulators, switches, polarimeters, magneto optical sensor, high power laser systems, magneto optical device, instruments and other wanted Faraday Effect applications, etc.

We equipped with advanced production equipments including cutting, grinding, polishing, fine-annealing, coating, testing instruments and extensive facilities to offer from diameter 0.90 mm to 300 mm and thickness max. 50 mm precision optics which are made of Faraday Rotator Glass Material.

Being actual manufacturer, our products have been distributed worldwide, we enable to guarantee you the production to excellent quality, reasonable price and delivery on time. The list of finished products and glass blocks in stock are available upon requested.
