OZ Optics’ ER-1000 series of benchtop polarization extinction ratio meters allows one to quickly measure the output extinction ratio of light from a fiber. A rotating polarizer measures the extinction ratio (ER) and the orientation of the transmission axis with respect to the key on the connector. As an option, neutral density filters can be added to the ER-1000 extinction ratio meters to extend the maximum power range. These filters can be easily inserted and removed, without disturbing your setup and allow power levels up to 2 W to be measured. The ER-1000 meters operate in several modes. In real time mode, the meter gives the extinction ratio and alignment. In logging mode, the meter gives the worst-case extinction ratio over a given time span. This mode is ideal for QA measurements. In addition, the meter can provide a relative power readout, proportional to the input power in dB. This readout is updated at up to 650 times per second. The computer interface allows the unit to be used with computer control units, for alignment purposes. The combination of polarization and relative power functions allows the unit to be used for complete auto-alignment of polarization maintaining components. Key Features:

Applications: Fiber Optic Component Manufacturing and Testing; PMC and PBS PER and Coupling Ratio Testing; PM Fiber Laser Diode Pigtailing; PM Fiber Patch Cord Production and Testing; PM Fiber Fusion Splice Testing; Automatic Alignment; Quality Control and Measurement; Product Development; Component and System Troubleshooting
