Ok... I did it
I decided to go ahead a dig out a Beam Splitter I had stashed away
Anyhow , Each module is producing 200mW of 660nm
I get about 350mW out as measured by a Scientech 365
Not too shabby!!!
This Pix shows the two modules aimed at a BS on the corner
of the aluminum block (It does not show in this pix)
One module has its diode mounted reverse polarization than the other!!!
This shows the beam as it hits the target at 6meters away
This is looking at the source from the target
I need to find more of these Beam Splitters...
I only have two of these and they are quite small 4.5 x 4.5mm
I have a bunch of others but they dont work so well...
