Faraday Rotators
Product description：
Faraday rotator provides non-reciprocal rotation while maintaining linear polarization. The plane of polarization will be rotated 45°when light transmits through the Faraday rotator in the forward direction and rotated additional 45°in the same relative direction with respect to magnetic field when light travels backwards from the reverse direction. It will effectively reject the light traveling backward.
CASTECH is dedicated to grow magneto-optical crystals with high Verdet constant and low absorption coefficient to ensure higher level reliability and less degradation. Combined with our unique high LIDT process technology, we are able to supply customized Faraday rotators for high power applications, up to 500W average power. The working wavelength of our Faraday rotator family ranges from 355nm to 4500nm, and the aperture is up to 45mm.
Applications
●Laser sensing system
●Ultrafast laser system
●OCT system
●Laser detection
Polarization Reference:
●All Faraday rotators non-reciprocally rotates the plane of polarized light in 45º.
●Extra half-wave plate for modifying output polarization is available on request.
