I briefly describe the laser optics used for CO2 lasers and the lens focal specifications and concepts to consider with the laser energy convergence after the lens.
Another helpful video on finding the focal length of your existing lens:

Great explanation, just one thing to add: the main reason you'd use a lens with a larger focal length is to achieve more square cuts with thicker material. Based on my experience, a 4" lens doesn't increase the cutting power compared to a 2" one.
Thank you so much, I've had my co2 for about 2 years and the mirrors / lens just burnt and need replacing and I was clueless with all the different types and focal length options. This was a great eye opener and gave me the info I needed! Thanks again!
Thank you! Very comprehensive and now i understand the difference!
thank you for this video. it's very usful!
You should do one that talks more in depth about increased optical aberration with the longer lenses. I mean you did sorta cover it, I'd just like see a little more in-depth discussion. The home built laser crowd has exponentially grown over the last few years due to opensource builds like the old lasersaur community. Now that parts and available data bases are more easily accessible, I've found the information base has been breached once again from there being a real lack of it. I recently started doing my part by opening up a facebook group "Laser Builders Guild" in response to seeing youtube channels like Furtherfabrication has made. There are a lot of various people that cover different areas of things related, but I've yet to see anyone that has a solid base of info on more than a couple things. It would be nice to see a more compiled weekly information dump in a cataloged structure based around your style, which I appreciate. You get to the point and have a well produced method of doing things that illustrates things fairly seamlessly. If you need topics recommended I can keep you busy!
Really good explanation, thanks
Great explanation, thank you very much
Great explanation thank you!
Helpfull video... thanks buddy !
Thank you. This definitely helped me understand this concept much better.
thank you, I love you!
Hi Patrick,
Can you share more on spot size? Does the target material and the processes like engraving, abrasion, fading, and marking effect the laser and mirror selection?
Thank you for this video. I always wondered what the different diameters on Focal Lenses for Laser Heads were for. I was under the impression that the diameter dimensions must have had something to do with what I was calling the "sweet-spot" of the focal point of a lens. I also was not aware that one diameter of focal lens was preferable for cutting and another one for engraving. I always thought that just knowing where this sweet spot was on your laser machine then by controlling the Z-axis platform then you can get your material as close as possible to the sweet spot and be able to do both cutting and engraving.
Thankyou . I'm just learning and this is great info 😀
May I ask what software you are drawing in during the video?
I've read about high resolution laser heads. It says it has 2- 2" or maybe 2- 1.500 lenses. Are they stacked. Are they Plano or meniscus lenses. And also. If just using one lense. Which is better for finer photo engraving details plano or meniscus? I'm wanting to make another head for my laser and want it HR but have no idea how it's set up. Thanks for your time
I got it regarding focal length why can't I find out about quality why I can buy a 14 dollar or 24 dollar or 59 dollar lens and do on. Whstvsbout quality of lense. Please help me with this
It is called rayleighlenght and is commonly known
