I tested 2 more optics today, the old PR2 that we took out and another optic I found in QIL. Both these optics are also not good for our purpose.

 

Polarization Incident Power [mW] Transmitted Power [mW] Transmission [ppm]
Existing PR2 p-pol 910 0.004 4.4
V2-1698 & V2-1700 p-pol 910 595 653846

I'll find thw Y1S optic and test that too. We should start looking for alternate solutions as well.
