The Luna NRT-250 uses the same innovative integrated-optic Lithium Niobate (LiNbO3) waveguide polarization-controller device for super-fast polarization response as the NRT-2500, but the NRT-250’s Tracker is field-programmable gate array (FPGA)-driven, creating an even faster device.
With fast, robust, endless polarization, Luna's unique tracking algorithm enables virtually perfect SOP tracking with no dropouts or ‘glitches’ for your new applications and prototypes, and its open architecture allows you to optimize the performance for your specific application, whether it's creating a unique error signal from four A/D converter inputs or optimizing algorithm parameters with Tracker’s optimizer program.
