This listing is for one G-8 Lens w/ Focus Ring. The G-8 is a high pass single lens but it wont increase the beam divergence like the G-2 does. The G-8 has a long focal length just like 3-element lens. Its a well-balanced lens that falls between the 3-element(divergence) and G-2(power). 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 12mm x 30mm modules when focusing to smallest point. 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 dont 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 dont 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 Im more than happy to help. Will not work with Fixed Focus models of Ortur LM2 or other cheap Chinese junk laser modules.
