Hi all, I have a cheap 3018 laser machine and I have focused the laser to its smallest point but it seems to give off quite a glow and having no prior experience, didn’t know if this is normal or affecting its performance? Picture attached
That looks like it could be a bad or dirty lens. Some of that effect is normal, but you normally have just a single bright spot in the center of the glow. You appear to have more of a ‘spray’ than a beam.
