@ ReNNo: no, i actually don't have access to CNC or tools, also for this it's all stopped ..... i really have no free time, in this period, and don't know when i can try, too.
@ RA_pierce: what expander have you used ? ..... the original one is already a damn high dioptry lens .....
That what i mean, basically, is this:
The first scheme is a standard module, where the expander enlarge the beam just few degrees ..... i was planning to add a piece of tube with a second negative lens, for expand it more, and substitute the original 6mm collimator with a 10mm lens in a second tube (so it come out from the front and can be focused), making the beam more "fat" at the start, but, hopefully, making it work like a "built-in beam expander", with the possibility to collimate it better at distance ..... i know that this probably cause a little loss of power, from the second negative lens, it was just an idea for an experiment, anyway .....
