I've recently noticed a "hole" down the center of the beam of my 445nm build using an A140 diode in a JayRob host. When I first noticed the "hole" I also heard a slight jiggle and narrowed it down to the lens assembly. Turns out the retaining ring on the back of the assembly had come a bit loose so I tightened that up but still the hole remains. I concluded that the obstacle is in the lens assembly because the diode itself produced a nice smooth pattern with no disruptions, just like it's supposed to. So my question then is, could it be a misalignment of the optics in the lens assembly? I would think that's the problem because I can see nothing in there at all, it seems clean. I apologize, I would provide pictures but my cameras are not working at the moment :yabbem:. It's a nearly perfect circle just off center in the oval produced by the diode, but again it is not being generated in the diode, it is the lens.
P.S. I got a picture uploaded to my "outside" album but had trouble uploading it to the post. Maybe that will help a bit.
Thanks in advance for any suggestions or input,
