The proof of concept module was hard to build. I used shims of 100 micrometers and a tweezer to set the height of the laser.  In the next module the build procedure is simplified so it is easier to scale the amount of single bundle transparent polygon scanners in the world from 1 to 10, and make a 10x improvement.
The procedure is as follows; turn the the laser diode so long axis is parallel with prism, set height laser, set height diode, focus laser by positioning first cylindrical lens.  Other components still need to be added an whole system needs testing. The current alignment setup cannot correct for the offset of the horizontal offset of the laser diode. This is a problem as the production of the laser housings is not consistent.
