850nm/980nm/1064nm/1550nm/2000nm Polarization Maintaining Polarizer PM Fiber Analyzer Slow Axis Working
The polarization-maintaining fiber in-line polarizer (analyzer) is designed to pass linearly polarized light and block random polarized light. It can also be used to enhance the extinction ratio of polarized signals. The maximum working wavelength range is up to 50nm, and the high polarization extinction ratio is extremely suitable for fiber network and polarization measurement, especially polarization analysis, control and monitoring. It is widely used in polarization-maintaining fiber amplifiers, polarization-maintaining fiber lasers and other products.
*CivilLaser can also provide depolarizers, please contact us if you need it.
