    Fulminex lasers

    Has anyone hear of the Fulminex company?. They are selling a few laser pointer models and giving few real details and what seems like exaggerated claims.

    Focusing problems

    Well, here in upstate NY in December, all I have to do is take it outside and exhale!!!!

    Focusing problems

    No, I never removed the lens from the head. I have since gotten the beam to a finer focus. Maybe I am being unrealistic by comparing the best focal point of this laser to that of my 3 watt blue unit. That thing focuses down to a tip of a needle point....

    Focusing problems

    The head makes 6 complete revolutions from being all the way in to just before it becomes loose and will come off. The lens within the head will make at least 6 full turns, if not more. I have counted the full extent of travel of the lens within the head. With the combination of the two; there...

    Focusing problems

    The glue wasn't too hard to overcome. There is plenty of travel for the lens within the head. It's going to be a matter of trial and error to zero-in on the lens position to get the focal point that I am looking for....the one that should have been pre-set by the manufacturer.

    I believe you are correct. I will continue to close in on it. Thanks

    Focusing problems

    I just put a beam expander on it and was able to get the tiny focal point size in front of the laser head like I did with the 3000mw Sanwu blue unit.

    Focusing problems

    That is the goal, exactly!...I can get a tiny point on the wall, 8 feet away, but I can't seem to get the same focus a few inches ahead of the aperture.

    Focusing problems

    For the person who asked if there was enough threads to adequately move the lens in and out; there seems to be plenty...and I was able to easily "break" the glue that was originally securing the lens. I can adjust the lens or head, or a combination of the two, so there is a very wide spot on the...

    Focusing problems

    I have a fairly new GX3, 200mw green laser that I bought from Big Lasers. My current guess is that I over-payed for this unit.... It has a strong beam and I don't dispute it's advertised power. The problem I am having is to get it to focus to a focal point. I also have a 3000mw Sanwu blue laser...

    focusing a Sanwu 445nm, 3000mw

    Well, the correct, 16340s will be delivered by this Saturday. I tried a few days ago with a black balloon and nothing!....then I used my 200mw 532nm green and it popped almost instantaneously....I will try again with the correct batteries and focus it as you suggest...then see where I go from...

    focusing a Sanwu 445nm, 3000mw

    Toward the end of this week, I should have the 16340 batteries for this laser....I will re-try everything with them and then decide if I got screwed over buying this thing from Sanwu.....I have been using non-rechargeable CR123a's while waiting for the 16340sw to arrive....maybe they ren't...

    focusing a Sanwu 445nm, 3000mw

    Well, I already contacted them regarding my dissatisfaction....I will wait for the 16340s to arrive, try it out then see where I am with it all.....
