This listing is for one G-8 Lens w/ Focus Ring. The G-8 is a high pass single lens but it won't increase the beam divergence like the G-2 does. The G-8 has a long focal length just like 3-element lens. It's a well-balanced lens that falls between the 3-element(divergence) and G-2(power).

"G-8" lenses with the lens recessed in the tube that are available from other sellers clip the edges of the laser beam which will greatly reduce output power. Be certain you are getting the The REAL G-8 Lens!

This is an excellent upgrade for many engraving machines including Ortur, Eleksmaker, Neje and many more! Don't be fooled by other sellers passing off inferior lenses as the G-8. Buy from a trusted source for all your diode laser needs.

Be aware that this will not work with the newer downgraded fixed focus laser modules being pushed out.

Specs:

90% efficiency, long focal length, and tight beam profile

Size: M9*0.5. Fits standard 12mm* modules and more.

Structure: Single Element

Package: 1pcs/package in Anti-static bag

*Please Note: Only a couple of threads will make contact on some laser diode modules when focusing to the smallest point. I highly suggest using some Teflon thread tape to help tighten the contact between threads.

I normally ship the same day or before the next available pick-up is available. Once your order is placed it will go out right away because I don't want you to have to wait any longer than you have to. Most orders are delivered within 3 business days in the continental US. International orders take longer of course but they have been getting delivered fairly quickly.

Please don't hesitate to contact me with ANY questions regarding my listing(s). I can offer a lot of technical assistance and/or point you in the right direction to find the answers you are looking for. I am usually very quick to respond and I'm more than happy to help.
