5) Slide the body of the resonant scanner inside its mount and then attach the mount to the alignment jig. Adjust the height of the resonant mirror such that it is at the same height as the alignment mirror. Height of the top edge of the resonant scan mirror should be is 2.7 mm above the top of the alignment block.
6) The orientation of the resonant mirror should now be adjusted such that it is parallel to the alignment mirror using an alignment laser. The alignment laser should hit the resonant mirror and the alignment mirror at the same time. Then adjust the orientation of the resonant mirror carefully so that the two reflections overlap.

From left to right: Alignment jig with resonant mirror and alignment mirror; height – the top edge of resonant mirror center should be aligned with top so that it is 2.7 mm above the edge of the alignment jig (2.7 mm between edges); close-up of laser beam hitting the resonant mirror and alignment mirror; reflection from the two mirrors before alignment; reflections after alignment – they are on top of each other.
7) At this point the resonant mirror can be mounted in the chamber. This is fairly tricky as it requires management of a fairly short cable and the holder needs to be mounted deep to the bottom of the resonant chamber.
Attach the cable to the mirror. Grab the resonant scanner mount with vice grip and insert into the chamber. The cable has to be trapped under the bottom of the mount - screw to the bottom of the chamber while pushing towards the alignment edge
