Hmm.. Me too. I'll try from my work email...

Not sure if this would help, but the silver focusing knobs from Sure Electronics don't go on the lens as far as the Aixiz focusing knobs go... hence letting the lens screw down further. I could send you a module IgorT if you think that would help. The modules are pretty cheap from Sure and would be a good all in one solution for these strange lenses... assuming that this slight difference would work.

If the diode is pressed into the module completelly, even the thickest rings work - with plastic lenses, that is. I have at least three different ring types here. As well as three different modules.


I have to make some pictures, and explain the differences. Because there are some other problems.

One of the DX modules has a ring with a very narrow apperture. It can actually reduce the power of a blu ray, since blu rays have such thick beams. This might not be a problem with the glass lens tho, as the beam will be slightly thinner. Need to check.

And another one of the DX modules has threads (which accept the lens nut), which don't extend the entire depth of the head. If someone has a diode in one of these modules, this could actually present a real problem.

I don't know which modules these are tho, as i always get a mixture..


EDIT: I assumed the thickest focusing rings are the ones, that accept a diffraction grating above the lens - the focused line for example.. But i just got some more modules, and a few have the thicker ring. That is the one that doesn't allow the lens in deep enough. Have to check with a fully inserted diode..

This means, there are at least four focusing ring models...

For those with lathes, it's easy to just machine the back of the the focus ring, so that it is a little thinner (allowing more room to screw the lens down). I have been doing this with 803T/AixiZ builds. Of course, without a lathe, it wouldn't look clean...

Does that mean it allows it to focus to infinity?

There is no such thing as "focusing to infinity"
It is impossible. You can never even get close to doing so.

For those without a lathe but have a drill, the drill chuck can be used to spin and in the other hand a file or sandpaper. Spin the metal in the drill and slowly reduce the desired area. I found this to be quite effective mainly because the metal is soft and easily worked. Now getting a perfect level edge can be a bit of a challenge, but practice takes you a long way with it.

Ya... i know that. That is just the term everybody uses.
The laserbeam will always diverge.

If you make it thinner, it will not cover as much of the lens nut, and allow the lens in much deeper, so yes you can then get a "parallel" beam with acrylics..


The glass lens has to be even closer, but partially, this can be solved by the position in the lens nut. I need to measure this position exactly, to prepare plans for the lens nut. I will take some time this weekend to do everything.


Here's a pic of the four focusing rings i got from DX..
1. Thin ring with a wide opening
2. Thicker ring with a too narrow opening
3. Rinng with diffraction gratings
4. The thickest ring

-The first one works just fine.
-The second one looks strange, and blocks a little around the edges of a blu ray beam.
-The third one is what i get when i order the "focused line" module. Even tho it's very thick, it actually has the most of the lens nut sticking out, because it has room for the diffraction grating above the lens nut.
-The fourth one is what i sometimes get from DX, but usually from AixiZ. This is the problematic one.


If you remove some from bellow, on #4, more of the nut sticks out. In some cases i screwed it onto the lens nut just with the first two threads, and fixed it in place permanently. I did this also, so that the ring would stick out further and i have more to grab when focusing..

I am in for one 650nm and one 405nm lens.

this is really looking good IgorT.

Re: 405nm AR glass lenses - fit AixiZ  FEELER

Skater: Just to clear something up... The metal focusing rings will not come with the lenses. It'll just be a len in the lens nut. People will have to take the plastic lens out of their laser, remove the ring and put it on the lens nut with the glass lens.

I'm showing everyone the focusing rings, so you know what to expect or what to do, if you're getting a lens and have one of these modules.. Many of us order from DX, and DX constantly changes manufacturers, or the manufacturers change the model.


But the rings are not really an issue. I am more worried about one type of the DX module, that has threads, which don't extend to the bottom. Theoretically it could happen, that the glass lens nut wouldn't go in deep enough.

I found one of these modules again today... I'm attaching a picture.. I marked the distance, that might be too short.

Some of them have this area threaded to the bottom. In others, the threads end a little higher, but they end just at the top of the diode, so it won't be a problem. But in the one in the picture the threaded area looks very short. I can't say for sure, if the lens nuts will go in deep enough to get a parallel beam with these.

I'll measure exactly how deep the lens has to go over the weekend, when i hopefully have some time. Then i'll measure how deep the lens nut goes into one of these, to figure out where the lens would have to be mounted in it.

It might work, but for now i would advise against using them for blu rays. It'll work for reds tho, as the FL is different there.


P.S. The potentially problematic modules have this small warning label, different from other models, but with all the changes i'm not sure they can be identified for sure, by the label alone.

When you are done doing measurements for the lens nut, will ring #4 still be a problem?

Re: 405nm AR glass lenses - fit AixiZ  FEELER

So how much are these looking to cost?

 

[IgorT]

Re: 405nm AR glass lenses - fit AixiZ  FEELER

Yeah, look at the pictures again.. Note how little of the plastic lens nut sticks out of the thickest ring.. It covers almost half of the lens nut. It would either have to be made thinner, like Jayrob suggested, or it could be fixed permanently on the top two threads of the lens nut. Making it thinner would be better.

It doesn't even allow plastic lenses in deep enough. The glass will have to be deeper. The position of the lens in the nut can offset this a little, but not enough for the thickest focusing ring.

Re: 405nm AR glass lenses - fit AixiZ  FEELER

If you run into a module like that and want the threads to go down further, ship it to me, and I'll be more than happy to tap the threads down all the way.
