Optical Instruments
The PERM is a benchtop polarization extinction ratio meter designed for precise measurement of polarization extinction ratio (PER) and polarization angle in polarization-maintaining (PM) fibers, making it ideal for testing PM components and connectors. It supports wavelength ranges from 400 nm to 2500 nm and features a front-panel connection port compatible with FC/PC (narrow- and wide-key), FC/APC (narrow- and wide-key), LC/PC, and SC/PC connectors, with adaptors. Additionally, it has an adaptor option for measuring bare fibers. A push-button operation initiates measurements, displaying PER and misalignment angle, while USB connection enables remote operation and data recording via a user-friendly GUI. The PERM operates using a rotating polarizer in front of a photodiode detector.

Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
Automatic Polarization Extinction Ratio Meter: Laboratory optical integration depends on preserving the optical budget through the complete path. The 900-1650, 1600-2500, 400-900, 357-403, 220-350 wavelength specification sets source and detector compatibility. The fiber/interface entry (None, Yes) must match the connected components.

Technical FAQ
Bare Fiber Adaptor: None, Yes · Connector: FC/PC/APC. Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
Wavelength: 900-1650, 1600-2500, 400-900, 357-403, 220-350. Check the Optical Instruments passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
Share your wavelength, fiber type, connector, power handling and control requirements and we will qualify the matching configuration and part number.
