Thorlabs PAN5710IR3 External Polarimeter Sensor Head – 1300-1700 nm (IR3) Fiber-Coupled Polarization Analyzer
This used Thorlabs PAN5710IR3 is an external sensor head designed for precise polarization measurement in the near-infrared spectrum from 1300 nm to 1700 nm. As part of Thorlabs’ PAX5710 series polarimetry system, this unit is intended to pair with a compatible TXP-series main unit (such as the PAX5710IR3-T) to form a complete polarimeter .
The PAN5710IR3 is a fiber-coupled device capable of measuring key polarization parameters including the Stokes parameters (S1, S2, S3), Degree of Polarization (DOP), azimuth, and ellipticity. It is widely used in research applications such as atmospheric turbulence studies on free-space optical (FSO) communication links and general fiber-optic polarization analysis .
Condition Note: This unit is untested and sold as-is. This listing is for the external sensor head only; the required TXP main unit is not included.
