The PSGA polarization measurement system is the most accurate product on the market for analyzing PMD, PDL and other polarization related properties of light sources and optical materials. The patented design utilizes magneto-optic crystals for high accuracy and repeatability.

The PSGA can be delivered with an internal tunable laser, but can also be used with third party lasers, to generate scans of DGD, SOPMD  and PDL. The instrument has an attached flip-top LCD display design and a VGA port for use with external displays.
