Faraday Rotators FR635-3-1.5W

Faraday Rotators — Model FR635-3-1.5W

Magneto-optical Faraday rotator, center wavelength 635 nm, Ø3.0 mm clear aperture, average power 1.5 W, rotation angle 45°±0.5°ᵃ.

Overview

LBTEK Faraday Rotators can be used to rotate the polarization plane of light beams and are widely applied in various laser systems, such as erbium-doped fiber amplifiers, optical switches, and optical modulators. They effectively prevent optical damage or system instability caused by harmful reflected light. LBTEK offers customization services for parameters including the center wavelength, clear aperture, and average power of the rotators. For any customization needs, please contact LBTEK Technical Support.
