Agilent / HP / Keysight 8169A
8169A Polarization Controller
This unit is used to change light from any polarized or unpolarized light source into any well-defined state of polarization.
The design based on bulk-optic zero-order waveplates and a high performance linear polarizer at the input provides optimum determination and repeatability of polarization states over a wide wavelength range.
Its especially well suited for use together with a tunable laser to make swept-wavelength measurements of the polarization dependence of fiberoptic devices, by setting a set of relatively orthogonal polarization states for Mueller Matrix analysis.
These measurements are supported by a Plug&Play driver and coordinated operation of this unit with an tunable laser and power meters can be enhanced with the Photonic Foundations Library software package.
The fundamental basis of this flexible instrument also supports many general applications requiring polarization control and analysis.
Accepts high input power levels and polarized or unpolarized light sources.
Accurate, repeatable output polarization reduces test setup time and
Flexible attachment with interchangeable connector adapters.
Built-in algorithms for controlled polarization scanning.
High accuracy and repeatability of output polarization state: +/-0.09° on Poincar Sphere.
Low wavelength dependence of output polarization state: +/- 0.1°/nm on Poincar Sphere.
Polarization Extinction ratio >45dB (1530nm - 1560nm).
