OZ Optics Ltd. has debuted a new line of bench-top test instruments for polarization maintaining component and device testing. The Polarization Extinction Ratio (ER) Meter analyzes light from a fiber and reports the polarization extinction ratio in decibels. It also reports on the orientation of the polarization with respect to the connector key on the fiber.
The system can measure extinction ratios of up to 50 dB; the orientation can be determined with 0.3 degree resolution.
The meter operates in either real-time or test mode. In real-time mode, the meter reports the current polarization, updating the result several times per second. This mode can aide optics alignment. In test mode, the unit monitors the output polarization over an extended interval while the fiber or device is subjected to stress. Operators will use this mode for quality testing of the fiber at a manufacturing or testing station.
ER meters are available for operating wavelengths ranging from 450 to 2,400 nm. An optional attenuator enables measurements with output powers as large as 2 W. Various connector interfaces, including FC, SC, LC, and E2000 connectors are offered, and can be easily interchanged by the user.
Touch screen interfaces, built-in memory and USB 2.0 communication/controls provide ease of use as well as the ability to streamline and automate the measurement process.
