FBERPRO's Polarization Extinction Ratio Meter, ER2000, measures the Polarization Extinction Ratio(PER), Polarization Angle and Power with high accuracy and fast speed. ER2000 also provides the functions such as, holding minimum PER during measurement, and relative-power monitoring function. The main applications of ER2000 are to characterize the PER of Polarization Maintaining(PM) Devices, and to align the PM fiber to laser diode, polarizer, and PM devices at affordable price.
