NUBM44-v2 divergence at 3 meters

Does anyone have any pics or measurements of what size bar a NUBM44-v2 would produce at 3 meters using a standard lens like a G8 or G2. I’m not concerned with power loss at the lens. I’ve seen some other threads that deal with much longer distances and those show a massive spread.

I’m looking to put as much power as possible into a dot 3m away into a diameter of 1-5mm. Color doesn’t matter to me if there’s a better or lower/higher wattage diode with smaller divergence specs. You know those videos on wicked lasers (I know there’s no love for them here) of popping a ballon or lighting a match across the room? That’s essentially what I’m goin for.

I’d like to stay in the 3watt+ diode range so when this little project is over I can retask the diode into something useful like one of those cheap 2D laser engravers.

And.... make a hell of a better burner out of it when focused down to a spot too, RCB found that out when he first did so.
