We took a bunch of photos on HAM7 and SQZT7 today, the IR-green coalignment is fixed.
IR-green coalignment: on the iris between ZM3 and FC1 (before and after) and after AM3 (green and red overlap)
Beam position for all 3 irises placed in HAM7:
Iris 1 IR position on the iris placed between ZM1 and ZM2.
Iris 2 IR+green position on the iris placed between ZM3 and FC1.
Iris 3 IR position on the iris placed between BM4 and ZM4, with "RL" on the Thorlabs IR card placed on the iris as a reference to estimate the deviation from the center of the iris.
For 2 irises placed on SQZT7 HD path:
Iris 1 IR position on iris1 on SQZT7.
Iris 2 IR position on iris2 on SQZT7.
We also checked the IR on HAM7 QPDs path, the IR is off centered on the lens (seen from both front and back). This was roughly centered, and will be fine tuned with the picos.
