Postscreening	aligned with respect to upstream camera image in elog (no downstream camera image available)→ flipped the cell (keeping the same orientation) c2c nd=30.9 c2 coupler cyl nd=9.8 c2 coupler pis nd=18.8 30.9/1.66 - 9.8/1.66 - 18.8/1.66= 1 um ...but coupler was supposed to be 5 um? Possibly deformed and measuring in different positions. But at least coupler is suspended in this case. Tried to measure directly opposite final point on the cyl and got nothing or large fringes. So probably not well suspended in centre i.e. 30.9/1.66 -18.8/1.66=7 um so again, maybe a few microns of space round the center, with coupler close to cylinder. 30.9/1.66 = 18.6 agrees with above finding.
