Realy good
This lens is realy high quality and it fits gatling series laser
3-element lens (Cleanest beam profile, best for low power lasers) 3-element lens has a long focal length, low divergence and clean beam profile Advantage Tight laser beam with the cleanest beam profile Downsides 70% efficiency (1W raw output from the laser diode would be down to 700mw) G2 lens(best for power) The G2 is a single lens enabling the maximum true power of the laser diode f or rapid close-range burning and engraving. Advantage 95% efficiency, reduces the beam aperture Downsides Increases the beam divergence (thickness) and affects the beam profile G7 lens(Balanced Multi-Purpose Perfection) This lens is a cross between the divergence and the power lens. With the G7, the beam divergence won't increase as it does with the G2 and you will still get very close power of the laser diode. Advantage 88% efficiency, long focal length and increases beam apertrue

You just think your laser will burn until you install one of these G2 lenses and see what it can really do. The G2 lense will definitely increase divergence but you can still make a nice beam at night with the beam expander installed. First picture is burning wood. Other 3 pictures is lighting a citronella candle.
I use the 3 element lens in microscopy. Compared to all other lenses....it gave me the cleanest beam.surprisingl the power loss is not that big.
