5) Slide the body of the resonant scanner inside its mount and then attach the mount to the resonant mirror alignment jig. Adjust the height of the resonant mirror such that the top of the resonant scan mirror is 2.7 mm above the top of the alignment block. The alignment jig itself is unnecessary here, as it is only being used to set the height of the resonant mirror in its mount, which can be done in alternate ways (look at dimensions in DWFX assembly file, for example).
The picture on the left may be ignored. The mirror being cemented on here is unnecessary. The picture on the right shows the resonant mirror being adjusted for height, and approximate angle.

8) After mounting the mirror make sure to get all of the dust out of the chamber and seal it up with an O-ring and lid. There is no need to screw the lid down now, as it will need to be removed when the chamber is mounted to the vertical breadboard.
The following procedures will need to be completed after the modules are mounted on the microscope breadboard, and after the beam is aligned through the remote focus assembly
9) RemoveSince the beam should now be aligned with the remote focus objective aperture, and the remote focus mirror should be well aligned
