Datasheet

Overview

The Luna POD-001 is an in-line polarimeter designed for low-cost, high-speed polarization characterization without interrupting data traffic. It outputs four voltage signals that are used to calculate both the degree of polarization (DOP) and the state of polarization (SOP) of the light passing through the device, with results available in microseconds.

The device, marketed as PolaDetect™, is intended for integration into polarization monitoring and polarization stabilization modules, or into polarization characterization instruments. It is supplied with a preamplification board that provides analog signals for SOP/DOP calculation, feedback control and a computer interface. A calibration matrix for the calculation is provided with every device.

Versions without the preamplification board and calibration matrix are also available for OEM purposes.

The POD-001 has been discontinued by the manufacturer. The POD-201 polarimeter is listed as a similar product.
