- LINKS BELOW: As of Sept 2023 there are 4 laser nozzle upgrades available for the OMTech Polar and Gweike Cloud. Three are sold on Etsy and one is sold by American Photonics. If you choose to go with American Photonics, please consider using 5% discount code LASERGUYS.
Video corrections: I misspoke and said the American Photonics lens had a new focal distance of 53.8 mm if you reference off the plate. It’s actually the other way around. It’s 47.8 mm from the plate because the AP lens sits 3 mm higher. 47.8mm + 3mm equals 50.8. If you did 53.8 then your focal distance would be 56.8 making it out of focus.

American Photonics 5% Code: LASERGUYS
Thanks for the video Cam! I was reading up on this topic in the FB group and last week I ordered the AP kit and it should be arriving today. After watching this review, I'm happy that I made that decision. Hope to get these running this weekend!
I use the American Photonics rig. Until I saw this video I was not aware that I had to compensate the focal distance another 3mm for this nozzle. That explains a lot of the inconsistency I've been getting in cuts. Thanks for the great info!
Is that 3mm added or 3mm subtracted from 17mm? No real explanation on their sight.
I am in the same boat as you. I believe it is added to the 17 since it is 3mm shorter than the stock. So the new offset is 20. would love a confirmation on this.@@jeffgraves4564
@jeffgraves4564 I actually do my measurement using the 58mm distance from the base of the platform to the top of the material. With this nozzle, I reduce the distance to 47.8mm. In fact I created a little jig to do the measurement, and it works great. No more out-of-focus issues.
Great video. Got the American phonics one. Could you do a video on setting focal distances for all the lenses? Are they the same? 2.0 2.5 4.0. The test cut files provided by omtech do not work with them how the videos ive seen to compare with standard. Seems to need more power? First c02 laser! Managed to get it cut 3mm basswood provided by omtech but at 20/60 which seems high??? I used their focal gauge
Excellent video and information
Thank you!
Great information Cam, I'll be watching to see how well the air assist behaves on the American Photonics. I have both the Swedish design and the Fiore design units...too bad my Polar is still in the shipping crate !! Maybe this will be the week I can get it out. Charlie in Central Ohio
Once you pull the polar out and set it up, I recommend swapping the stock lens for the Fiore or Swedish nozzle right off the bat. Both are great performing nozzles. I just dont like how the Swenglish Maker has his nozzle 3D printed.
Hey Ed, Have you given the DSA a whirl yet? My wife got me one for Xmas and I saw a post someone else wrote ya that he started the nozzle/lens was approx 1.5mm higher than the stock. So would that mean that instead of 17mm - material thickness... It should be now 18.5mm -material thickness? Haven't used as of yet cause I've been a lil ill as of late but plan on trying it out sometime around mid February n was wondering if that focal length is confirmed. Thk U n I subscribed!
I've got all of them
AP is my go-to - but I REALLY wish it had a better air hose fitting than the stock elbow.
DA is 3mm in height. I had clearance issues with it, but that could have been my use case (1/4" ply, cutting tiny pieces that would lodge under the nozzle)
The Fior is a solid option, but I broke a lens trying to remove it for cleaning (it "flipped" out as I was removing it and it shattered on the tray).
The 3D printed one is just not solid enough.
Sounds like we’re in line. Fiore design with the AP magnetized lens would be the bees knees.
@@EdmondsWoodshop 100% -
My ideal:
The Fior metal air assist nozzle, with the AP magnetic lens and copper tip, in the all metal body of the DA - with zero height adjustment from the stock
Thats my wishlist, anyway :)
Do you know when an all metal Fiore will be released?
Hello. I cleaned my omtec polar yesterday. And now my laser cuts, but the laser does not cut as thin as before.
Great review. A 3d printed nozzle would make sense from a design point of view as you could combine the best parts of all the nozzles. The downside being strength and burning. I wonder though .. what the Swenglish Maker is printed from? There are some high-tech resins available I know.
The Swenglish nozzle performs great. In fact, they all do with the right lens. However, I can see how appealing the swenglish nozzle may be because of the price. Per the listing the material is printed from yratech Resin Blu-Tough Nylon in black. I looked at the MSDS and it listed the melting point as "-" meaning not listed. The flashpoint is around 110 celsius. Unfortunately I haven't used it long enough to see if they durability maintains itself over long periods of heat exposure.
Looking at the resin .. it's pretty tough. I am thinking that the part that the air assist hose hooks to could be replace by brass .. just print the nozzle with a hole for a brass hose fitting. The same thing for the open end where you were talking about possible melting if the laser hit it. Simply make that out of brass. I like the magnetic lens holder method that American Photonics uses. Cool stuff. I have a lathe and 3d printer so that is all "dooable". I subscribed the other day .. even if you appear to be a former grunt. :) .. former CDAT here. @@EdmondsWoodshop
Thank you, can you explain how to compensate with the AP set up? I use the the subtract from 17 and the plastic tool method, at this point.
They actually include a new gauge/ruler to use in their kit. You take their plastic gauge and rest it on the black plate of the laser head and lower the head until the bottom of the gauge touches the top of the work surface. That’s how you manually do it.
@@EdmondsWoodshop Thank you for such a prompt reply. Your videos have been a life saver.
How do you lower manually. If I push the down arrow it lowers the lens unit all the way to the surface? Sorry, real newbie.
Purchased ap lens. The only complaint would be using stack plastic air assist connector. Tried to find a 45degree 6mm threade barb with out any luck. Did find a 90 but angle
is off for hose connection. No luck finding a stock one either. Hoping someone makes a 3d file for resin printing. At the least. Love the videos.
Agreed. I mentioned this to Steve Walters (owner of AP). When you put plastic into metal, it'll deform. I'm wondering if the making a push to connect fitting that small.
@@EdmondsWoodshop I have looked everywhere for a push connect also. Found 1/8 American but no luck on 6mm. Fastenal ,Grainger,Amazon etc. I was actually considering a brake line and tapping one end to 6mm and flaring the other side just haven't got that ambitious yet. Thanks for the response.
Can you tell me if there is an alternate option for the stock air assist tube adapter to go with the American Photonics setup?
At the time I made this video there was not an aftermarket air assist adapter available. You may need to ask American photonics
@@EdmondsWoodshop Thank you for your response. I have sent them a message as well. You answered faster 😂
Nize just bout the aluminum one 2 days ago. Are you gonna put the red dot on yours?
I actually have the mas effect red dot already. I removed it for the video as it can be distracting
@EdmondsWoodshop just started watching the cleaning video n saw it.
heh; assuming we don't just jam a qtip up the mounted lense by removing the tray.
Just bought the american; it had me at "easy cleaning".
Haha no. That’s not a very effective way. The American photonics will be much easier to deal with. You can also clean the tube while it’s mounted which I like
The DSA lense is 1.5mm higher. Steve said its actually 3.1mm higher.
Thanks for confirming the DSA. As far as the AP lens, I spoke with Steve on a video chat and 3mm is what he told me. In terms of focus the difference between 3 and 3.1 isn’t going to be seen by the people that are using this setup.
Sorry lol, thought your name was Edmond but saw other comments calling you Cam... My bad
The Swenglish maker laser nozzle failed (shown in this post)
