I was wondering if anyone has replaced the lenses in the 10w with compound lenses to tighten the focal point. I want to get a set but I cant find any information on the sites that carry them about the snapmaker setup. Any info or links you can provide would be appreciated.
Thanks

You need finer than 0.05 mm Ć 0.2 mm?
The linear modules only have a SM claimed accuracy of .04mm.

Where are you getting those specs and what does the first nomber represent? All the specs I have found refer to a .2 mm dot and yes I would like to get this down to .1mm
Here is a link explaining my reasons. How to Photo Engrave Tile with the Norton White Tile Method ā OMTech Laser.
I didnt check the store but was looking through the support and only found the 1.6w. However that still doesnt explain what the 0.05mm refers to unless this āSpotā is oblong in which case I definately want to refocus.
I think thatās just the nature of the dual diodes. Most of the lasers with that setup like the Xtool, Ortur are also oblong.

Each of the laser diodes themselves produce an elliptical beam, and focusing canāt change that. You would need an elaborate lens system in order to change the shape of the beam.
have either of you looked at the link I provided,? The āelaborate lens setupā you refer to is called āCompound lensesā and they are designed to do Exactly what I refer toā¦ I may not have had my laser very long but I have tried to do my research on the artwork and at the very least when someone ask a question and provides a link for reference I would take the time to look at it before I tell him that focusing cant change the shape of the beam. See this link for reference and education. High Resolution AR Coated Lens - J Tech Photonics, Inc.
So I repeat has anyone used a compound lense on the snapmaker or have reliable information about them. I do not need information about what someone thinks that has never used, seen or heard about such items.
I suggest that you reread the content at both of your links, as the statements you have made are inaccurate and incorrect. What I stated is accurate and true. The only thing that a CO2 laser and a Diode laser have in common is the word laser.
Good luck

Yes, as CNC-Maker states it. A laser diode is nothing like a gas laser or a solid state laser using a cylindrical rod (like in a ruby laser).
The laser diode light emitting substrates have a rectangular shape, most of them not quadratic rather than with different dimensions for width and length. That makes it even worse.
It would take an āimpossible lensā to project a square original into a circular image of it. AFAIK, there is no lens geometry in optics being able to do that. The work-around often is to use two staggered cylindrical lenses, but this creates its other own problems. These maybe called compund lenses. They still canāt create a perfect circular image.
The bottom line is that you canāt turn a square image into a circular one optically.
Well, a pinhole filter like in a pinhole camera? No, the laser power would burn it quickly where its hit by the light not passing through the whole at the edge of the pinhole.
āCompound lensā simply means that it is a lens system composed of multiple lenses (elements) on a single axis. There is an infinite possible combination of lens sizes, shapes and types that can be used to form a compound lens.
