From left to right: Alignment jig with resonant mirror and alignment mirror; 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; height – resonant mirror center should be aligned with top edge of alignment jig (2.7 mm between edges).
5) 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.
Attach the cable to the mirror
Grab the resonant scanner mount with vice grip and inser 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

The goal is to couple the lens onto the PMT face with oil
Seal the edge of the PMT face to the PMT housing with 5 min epoxy - careful not to soil the plate above the photocathode
Add 30 - 50 ul of high viscosity oil
Place condensor lens on oil. Make sure there are no bubbles and carefully remove overflow oil from the housing.
Place a thin ring of quick seal (WPI) on the PMT housing around the lens

The PBS needs to have the three sides marked by arrows facing the beam.
The beam needs to be flush with the alignment edges on the mount
The UV transmission of the cube is low, so be sure to expose the glue to UV for ~ 2 minutes or so
