The polarization is retained in both beams. Previously, a beam splitter and a retardation plate were required for this process. The manufacturer has now succeeded in combining both functions in one look. In this way, the construction and maintenance of the entire system can be considerably accelerated in the future.

The original design is for 1030 nm and 515 nm. Wavelengths, polarization and reflection / transmission ratio can be individually adjusted depending on the application.
