LUNA PSGA-101 – Polarisation Measurement System
- Fixed crystal accuracy in a swept system
- USB removable data storage
- GPIB port for control of third party lases
- Ethernet for remote operation
The LUNA PSGA polarisation measurement system is the most accurate product on the market for analysing PMD, PDL and other polarisation related properties of light sources and optical materials. The patented design utilises 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.
