A Big Thanks To RyanElectro!

Yup and the other difference is that the Aixiz lens has some correction, allowing a more dot-like projection. While the G lenses focuses to a much longer, thin line instead.

Correction? :wtf:

It clips and has slower divergence, where is the correction in that?
Both are collimators, not secondary optics.

Last time I checked, the aixiz lens does not contain a long fl cylinder lens
to correct astigmatism :thinking:

Unless you have some new and interesting lens we are not aware of..

Oops, I used that word with its English meaning. I didn't know correction was a scientific term. I say correction because it "corrects" the beam to our preference. What does correction mean in the scientific sense? Does it only apply to certain types of lenses that perform a certain type of light manipulation?

 

[yobresal]

What aixiz lenses are you using that correct the multi-mode output substantially and result in a clean circular dot? Please point me in that direction. I would love it if these existed in reality.

Also, the line doesn't become longer with the G lens, it's just that the Aixiz clips the beam a lot more with its very small NA compared to the G's high NA.

Translation: "The line isn't longer with the G lens, its just shorter with the aixiz."
LOL

Are you being sarcastic? I can't tell. But I'm socially handicapped too so LOL sorry =P

And just the normal Aixiz lenses. I'll take some photos of what I mean, but don't you guys know what I'm talking about? The Aixiz produces a really clean, i would say almost perfectly circular dot to the naked eye, while the G lens produces a very fine line instead. Am I really far-fetched with this? I don't have any Aixiz lens right now but when I do, I'll take some photos with the two lenses in comparison on a wall, because if its not true then I must be hallucinating haha.

I second that! With what hes describing, it would eliminate the need for
all that extra work.

@ryanelectro

Less posting, more reading :wave:

What you have described to your 'customer' would take a setup like this..

-cylindrical lens for correction, and prism pair to shape or 'circularize'.

The differences you have noted are non existent. There are 2 differences
as mentioned in my post above.

Regarding the aixiz lens, the "correction" is pretty substantial in my perception, it's totally different when focused compared to the G lens. Almost night and day. One is a near circular dot, the other a very fine line. Total difference, at least perceived by me. I'm surprised you guys don't feel the same way actually. Maybe it isn't so much different to the person who's used to seeing it for years.

Correction: If you read the conversation, I did not describe to my customer (no need for apostrophes) anything regarding lens correction. Only that the line projection on a wall is normal for a G lens.

Second Correction: It's not about less posting. I barely even post anymore if you haven't realized. And for every post I post, I do read about 20. Especially since I have a huge thirst for knowledge. So not sure what you're trying to say here. Sometimes you can't find the right threads, sometimes you have a hellish week, sometimes you forget what you read, sometimes you don't understand, for those times, there are people like you

A simple answer and some advice is nice, but when coupled with indirect attempts to put me down -->
1) "Less posting, more reading" when the fact is I barely post anymore and have read tons more than post &
2) "What you have described to your 'customer'" as if my "customer" (in apostrophes) is a fake. And since when did I describe to my customer about something that needed such a setup? All I said was that the line projection from a G lens is normal.

Very subtle things in the post, but I do tend to see these little things. Maybe it's just me over analyzing it. If so, then sorry.

Regarding correction (scientifically)... What do you mean cylindrical lenses for correction. What do they correct? I notice you say circularize in another instance where I would say "correct". It seems like correction has a very specific definition. Because if not, then you would say the prism pair will be used to correct, but you used another word for that.

Also as the light passes through L2, what happens there? Looks unnecessary, but obviously it's not lol.

 

[TacoHerder]

Yall people are crazy... It took me a whole 5 seconds to understand what he meant by the dot line vs rectangular line you get with the G-2....

yobresal, correct me if im wrong. but he never said his aixiz lens he used corrected the multi-mode output substantially and resulted in a clean circular dot. In the conversation he simply stated that the G-2 is giving the beam a more rectangular dot. Sure, I guess he should have stated that the M140 diode(which i assume he used) doesn't produce a nice solid "dot" to begin with. But what he said was still correct, the G-2 lens( from pictures Ive seen) do appear to give the dot a more rectangular dot.

It appears, ya'll already love busting his balls. You could at least refrain from the troll like post that don't help out one bit.

 

[yobresal]

But normal lenses (the Aixiz) correct this behaviour very substantially and results in a very clean, circular dot. While the G lens does not, and thus produces a fine line instead.

Yeah, he said it right above. Not making this stuff up, just commenting on it because it is completely false and I don't want people asking me for these miraculous aixiz lenses with their lasers they buy from me.... the same ones Ryan is using in his. Get it now?

 

[TacoHerder]

well I stand corrected. I just think he chose the wrong words. Either way you are correct

 

[RyanElectro]

The aixiz lens can be "shaped" into a near circular dot while the G-lenses can't, they're always a line.

& haha.. miraculous lenses. OMG that should be the name of my lens LOL. Funny how we're talking about lenses when I have actually been designing a lens assembly recently.

 

[daguin]

Instead of "explaining" why you are not wrong, why don't you simply listen to those trying to help you?

Words, especially in scientific areas, have agreed on meanings
You cannot change those meanings because you don't like them or because you don't understand them

The AixiZ does NOT "correct" the beam.
It clips off the ends of the beam to shorten the line
It is still always a line

If you do not yet understand the difference between "circularizing" vs. "correcting" and you have no idea what the use of the cylindrical lens at "L2" is,
PLEASE stop your "designing" of a lens assembly and take the time to learn about them

You are only going to cause yourself more trouble

Peace,

Wow, kinda feel bad for the reviewer. That will teach him next time to give a review.

 

[yobresal]

No worries bud, we are all here to help each other and further our collective knowledge. We just want to make sure that continues to happen

 

[jakeGT]

I was simply stating that in the text your customer provided, you provided him incorrect info... And being a forum of knowledge, I think everybody agrees that your customer ( wether he cares or not) should be provided the correct information.

 

[InfinitusEquitas]

Yeah... you're not the only one.

Also seeing as this thread clearly got the attention of a mod, what is it still doing in the General section as opposed to Reviews or Feedback where it belongs?

 

[JLSE]

The aixiz lens can be "shaped" into a near circular dot while the G-lenses can't, they're always a line.

They are both always a line... :banghead:

Again, your definitions are confusing... Both can be shaped. There is a reason
why most manufacturers us single element aspherics with multimode outputs.

Saying they cannot be shaped is just adding to the misinformation you keep listing
off in your posts.

I use the G1 in my dual builds, with correction, and in my labbies a prism
pair to circularize. The line which you say cannot "be shaped" is completely
false.



Statements like this:
