I'm considering the 86-711 2" 532nm PBS from Edmund Optics for the ETM HWS at the sites.

The effect on the transmission through the system, compared to the THorlabs PBS, is shown in the attached plot.
Conclusion: it looks almost as effective as the Thorlabs PBS with the added benefit of being 2" in diameter. |
