1064nm Polarization Maintaining Faraday Rotator Mirror with PM Panda fiber pigtails
1064nm Polarization Maintaining Faraday Rotator Mirror with PM Panda fiber pigtails
Faraday Rotator Mirrors (FRMs) are used in a number of fiber optic applications, including interferometric sensor systems. In general, FRM performance parameters are specified over a central wavelength and narrow temperature range. This means that the rotation angle will change over wavelength and temperature.
We now offers a compact form factor, broadband Faraday Rotator Mirrors that rotates the light 45 degrees (single pass) over a wavelength range of 1550 nm ± 15 nm, and a temperature range of -5°C to +70°C. With a constant rotation angle within this bandwidth and operating temperature range, the broadband FRM can reduce noise dramatically for interferometric sensor systems.
