500mw green laser focus adjust help

Got a problem with my laser. It's 500mw, 532nm, not focus adjustable.
So what can I do to make my laser be able to focus all the light into a single point and burn stuff even better? Is there any lens I should or what, because I can hardly find anything about this on google. Any help will be appreciated.
>inb4 use magnifying glass. Yeah, I've already tried and it didn't worked, dumbass.

Welcome from the wider world of the internet. We try to keep things more family-friendly here than they do on that site with greentext. If you can't adjust the focus easily, then you're out of luck unless you can add an optic or adjust the "fixed focus" ones to a different fix. Remember that lots of "500 mW Green" lasers have much of their output in the IR range, which is filtered out in nice lasers. Bad ones send out a higher-power IR spot that reflects from surprising surfaces.

So: Is it really half a watt of green output? Can you get to the diode to adjust it? And have you tried LaserPointerForums?

Use a magnifying glass. And goggles.
