We selected the lens, adjusted, and fix the camera stage on EY. Resulting image is attached.
Also 50m (10m x 5) Dsub 15pin cable is placed for the EY oplev QPD. Connecting to the EY rack did not finish because we still need to bring a whitening board and two Dsub 9 pin cables. Should be finished on monday.
To illuminate in the chamber, a LED light source was placed in the chamber. After taking this screenshot, the light source was taken out, so now it would become just dark.
Note that the surface of the mirror is covered by first-contact now, and that's why some line-like patterns are found on the surface of the mirror.
