Any one seen this? Axixz Glass lens for 405 nm

[jayrob]

Jayrob could you be so kind as to repeat his test with one of your lenses?

I just did a 1' and 5' power comparison with a PHR/405-G-1 build and got very different results...

* RA_pierce got 157mW's at 1', and 129mW's at 5'. Difference - 28mW's, which is about 18% of 157mW's.

* I got 131mW's at 1', and 126mW's at 5'. Difference - 5mW's, which is about 3.5% of 131mW's.

Coherent PowerMax 5200 with PM3 thermal head.

Hey John Law, why don't you send Dave one of your RPL's. It will cut down on your wifes nagging.........LOL.......rob

Edit:
Aixiz 405nm glass lens:
140mW @ 1"
137mW @ 5'
Less than 3% loss

Seem RA retested and you guys got almost identical results.
I recheck my 405-g-1 lens and it seemed it was not focusing as far as I needed. It was in a custom mount that I tapped myself, but appearently not deep enough. I milled a little bit off the end of my lens housing and now I'm getting the Divergence I desire. Hopefully those Aixiz are at least decent and I didn't waste my money. I am going to do a side by side comparision myself to see if the power loss is worth the "possible" better beam quality. But again, at $15 its worth checking out, just wish I hadn't ordered 3 because now that my 405-g-1 lens works for my Infinite Color Build I only need 2 at most.

Just in case there was a misunderstanding I thought I'd clarify:

My test was done with PHR sled optics, rather than the 405-G-1 lens (that I sold) with the assumption that the results would be similar because beam profile is almost identical.
So it was by no means meant to be a definitive result.
My second test was done with the 405 Aixiz lens.
Tested with Laserbee LPM.
Thanks for the numbers Jayrob

Sounds like our results are very similar...

Thanks for the clarification!

Is this a triple element spherical lens like their 660nm coated glass one, or a single element aspheric lens?

 

[john_lawson]

maybe somone can lathe up a nice aluminum focus ring for these then?

i used jb weld and it worked great with an acylic focus ring

 

[Tabish]

Ordered one.
Hopefully it will be a simple swap with the regular lense in the aixiz module.
Cant wait for the stuff to get here for my phr build !!!!

 

[john_lawson]

it looks the exact same after i glued it into place it just has 4 more threads than an acrylic type

 

[Tabish]

Where do you glue it exactly lol
4 more threads ?
