Hi all,
I've been working on a 2W 462nm build for a while now, and tonight I was able to fire it properly (outside at full power with a glass 3-element lens) for the first time. However, I'm noticing that there's still some scatter occurring out to the sides along the same plane where the out-of-focus beam spreads. (see image)
How can I get rid of these artefacts? Is this something I can fix with focusing? Do I need to replace the lens? Is it simply inherent to the diode? My goal is the cleanest, tightest long-range beam, not engraving or burning. (unless I can burn at a distance)
