 Title: Diffusion ULE spherical mirror (S3) vs Fused Silicate injection planar mirror (P1) 

Observation made with IR Beam Viewer: 

The observation of P1 and S3 simultaneously while locking shows much higher diffusion on the ULE mirror. The diffusion on the two other ULE mirrors (S2 and P4) shows similar diffusion as S3.
