Sanwu G2 G7 Collimated Lens

You can replace the lens to upgrade your laser performance.

The lens will come with a 9mm Holder.

G2 lens(best for power)
The G2 is a single lens enabling the maximum true power of the laser diode for rapid close-range burning and engraving.

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.
