Luna’s POD 2000 is a DSP-powered polarimeter designed for high-speed polarization characterization, analysis, and monitoring. It utilizes four channels to simultaneously capture the four Stokes parameters, allowing it to measure an input light beam’s instantaneous state of polarization (SOP) and degree of polarization (DOP).

With a USB 2.0 interface, data can be directly transferred to a computer, enabling the polarimeter to monitor and analyze rapid polarization changes at a sampling rate of up to 100 KS/s. Additionally, it supports standard 100BASE-TX Ethernet for measurement and control.

The POD 2000 features a user interface that provides real-time graphical displays of the polarization state. This can be viewed on a Poincaré Sphere window for SOP traces or on an oscilloscope window for tracking polarization changes over time.

Key features:

• High speed, SOP/DOP measurement with 100Khz date update rate
