Hi guys just a quick one.
I would not recommend using a 3 element with a NUBM07E diode, or any other high power diode for that matter. I just finished a custom build in a Sinner Phobos and the diode was set a exactly 4 A with an SXD. I have never used a 3 element with these diodes, but thats what the member wanted. The beam looked very good when I set up the focus and all was working well until I tried to LPM it. At that point it hit 700 mW and I thought maybe my LPM was messing around. Shining it in the room however confirmed this as the beam was barely visible. The power dropped to 400 mW with a G9 and 200 with a 3 element.
Moral of the story do not use 3 element lenses with high power diodes. To be honest I wouldnt have done it, but for the posts in the forum where people said they have actually used them. I never actually liked the idea of a 3 element with an M140 let alone one of these diodes, due to the possibility of back reflections, but I guess I got complacent. :beer:
