We measured loss of new faraday. We made BAB top on resonance of OPO by hand. Loss of new faraday and HWP and f = 100 mm lens is 3% as follows.
| position | BAB power (uW) |
| before faraday and f = 100 mm lens | 395 |
| after faraday and HWP | 383 |
We also measured loss between PBS and PR chamber. Loss between PBS and PR chamber is 1.3%.
| position | BAB power (uW) |
| before PBS | 389 |
| after PBS | 388 |
| before PR chamber | 384 |
