I received a custom acrylic mount for cylindrical lens, that CDBEAM manufactured. This made the alignment of the glass painless. All the slipping and bumping getting them correct and level is now gone. These are great I know i'll be trying to purchase a second or third. I know he is kicking the idea around of selling these. So if interested let him know!
This one was for a 19mm beam height, but I know he can accommodate whatever is needed.
