I saw your article How Night Vision Devices Work, and I really liked it. I would like information on how to assemble the image enlarger tube.
Apparently simple in construction, as it is formed by plates in a tube, it is not something that can be done at home. The tube must have a vacuum inside it and the plates, in addition to special materials, have extremely critical shapes and positioning. These valves can only be found ready-made and are very expensive. We have not seen any suppliers for them yet. We just found the device ready.
