After a break for other projects I am back investigating the poperties of a super high intensity small diameter 30 watt RF CO2 beam
A long time ago i had established that setting my cheap Chinese 5030 RF machine to run at 1400 mm/s was a waste of time because the 30 watts of power was anable to support normal engraving at more than 500mm/s and photo replication was near impossible, even at 200mm/s.
By removing the commercial X2 beam expander and replacing it with my on beam "conditioner", allowed me to project the 3mm beam exiting the tube tube through to the middle of the work tabe
My intial experiments with lenses showed an unexpected inability of lenses to focus this small high intensity beam to make it a CUTTING monster. However, the geometry of very short focal length lenses showed hints of focussing ability
Putting the CUTTING dream aside I have done some more experiments with various compound lens configurations to see if I can exploit this high intensity beam in a different way .....for high speed photo replication.
