No, it isn't, I can focus it to infinity perfectly fine (just over 2mRad). It's just that the beam gets cropped by quite a bit because the raw output has 120° divergence for some damn reason. Might just be a defective diode. I'm probably better off just buying or building something else entirely. Already ordered a 1W 520nm PL-E Mini, that should be a good replacement.I guess the diode in your Gatling is set back a bit, too far back to collimate to infinity with that lens, the G2 has less than a 3 mm focal length to reach infinity focus, 2 point something, thus the "2". I should know, I'm loosing it, forgetting. I can now see why you want a shorter FL lens.
Actually, I never even intended to buy a gatling. I was going to do a 1.8A PLTB450B C6 build, but because I was talking so much about lasers, my dad bought me the gatling as a birthday surprise, but only told me when I had already ordered the G7 lens. It was cool for the first couple of days, but then, the lens got really fuzzy and I couldn't clean it, so I popped in the G7. The focusing mechanism is really loose too, and the lens keeps getting slightly off focus every few days, the heatsinking is pathetic, a ~2cm diameter brass disk with a not-so-heavy aluminum host, the included batteries were garbage, I ended up spending an extra 45€ on this thing, some 11€ for the lens and 33€ for some quality 16340s. I swear it just keeps giving me headaches. At least I can use the batteries with the PL-E Mini.
