The PEM-310 Polarization Extinction Ratio Meter provides accurate, real-time information about the polarization state of light in an optical fiber. Incorporating a rapidly-rotating polarizer and a high-sensitivity detector circuit, the PEM-310 can easily measure linear polarization extinction of 40 dB with a 10-Hz refresh rate. In addition, polarization angle and optical power are displayed on the instrument panel. To facilitate usage in production environments, the PEM-310 is fully controllable through the GPIB interface, and provides an analog output for external monitoring.
