G7 laser lens 10 watt+ laser · Black anodized focusing plateG7 laser lens Impressive engraving on plywood with G7 laser lens The G7 is a second best high pass single lens but it wont increase the beam divergence as the G2 does. The G7 has a long focal length just like a 3 elements lens. Its a well balanced lens that has the advantage of 3 element lens (very good divergence) and G2 (in terms of power). Optical transmission for 445 nm wavelength = 90% An efficient lens for 405 445 nm diode lasers. Optical
