Last year I was working on 7-color-laser that uses red, BR and green module. The problem is that BR and RED beam is much fatter than Green beam.
Red and BR diodes in Aixiz module give beam that is about 5mm in diameter and green module gives 1.5-2 mm beam in diameter.
When all three beams exit from sled only green beam is noticeable and other beams are almost impossible to see. (Because of its diameter)
Another problem of green module is that divergence is much worse than on BR and Red modules.
I was searching forum in order to find solution to make BR and RED beam thinner and concluded that it could be very expensive and I aim for the cheapest build.
If I could make green beam fatter that would solve my problem.
I have two theories that may solve my problem.
-- To use bigger lens with longer FL.
-- Or I can use different diffuser than would make beam fatter at the same distance from the lens.
If I could make beam fatter than would solve another problem, divergence. Right?
What others think about this?
Has anyone done that before?
Are my theories true?
Thanks!
