Hi,
I have two diodes in mounts as shown in the attached pics. They are driven by Robins module.
The beam that goes via the mirror (diode 1) is fine.
The beam from diode 2 is the problem.
However I rotate the diodes ( that is what the screws in the casing are for), the brightest beam goes straight through the cube. If I rotate diode 2, I can get the relected beam to almost zero, but the opposite is what I want. The beams are purposley mis-aligned so I can see the relative brightness of each.
I have tried swapping the diodes about, but no difference.
Anybody have any suggestions?
Thanks, David
