Faraday MOS-10
Faraday MOS-10
Description
Faraday MOS-10 is a type of Faraday glass that utilizes the Faraday effect to rotate the polarization of light passing through it. Faraday glasses are made of materials that exhibit a strong magneto-optical effect, such as heavy flint glasses and borosilicate crown glasses, and are commonly used in optical isolators, which are devices that allow light to pass through in one direction but block it in the opposite direction.
The MOS-10 designation refers to the specific type of Faraday glass used in the device, which has a high Verdet constant, a measure of the strength of the Faraday effect in a material. The MOS-10 Faraday glass is designed to operate in the near-infrared region of the electromagnetic spectrum, making it suitable for use in fiber-optic communications systems and other applications that require the transmission of infrared light.
Faraday MOS-10 devices are used in fiber-optic amplifiers and lasers to prevent unwanted feedback into the laser cavity and to ensure stable operation of the device. They are also used in high-power laser systems to control the polarization of light, similar to Faraday crystals like TGG (terbium gallium garnet).
