FS: 405-G-1 Glass Lens Mod - 31% Increase vs AixiZ!

Re: FS: 405-G-1 Glass Lens Mod-28% Increase vs Aix

FrancoRob said:
Ciao Traveller,
the increase is 28 %, and the further good characteristic is that it's a glass lens, thus capable to sustain really strong O.P., where the acrylics may only deteriorate..... this is why I'm waiting for a future success of the 8x..., 12x....etc...

Ebbene sì, se son rose fioriranno.... ;D

That's what I'm saying!...

This 405-G-1 glass lens will hold up for what ever host we want to put it into!  8-)

Hey Miloš, are you out there? Looking forward to more of your comments as promised...  :)

Re: FS: 405-G-1 Glass Lens Mod-28% Increase vs Aix

I got my two lenses the other day and just tried them out. They do seem to increase the power (haven't measured yet) but they can only focus out to about 6 inches.... I will not be using these lenses as this is a problem, they make the laser a very expensive flashlight.

Any tips Jay? Ive screwed the lenses out all the way and also in all the way, it seems as if they need to be screwed in further but there is no room. I'm using a shorter spring from a Sure Electronics module.. I'm using an Aixiz Module in a MXDL w/ your Ver1 heat sink... PHR803T and also 6x blu rays ( I have two lasers made).

thanks,
Kendall
 
Re: FS: 405-G-1 Glass Lens Mod-28% Increase vs Aix

I have them in several builds with AixiZ modules. Both PHR and 6X as well...

The only thing that could be different, is how far your diode is pressed into the back of the module. Now, I don't even press mine all the way in. I only press the diodes 'flush' with the back of the module. And I still get plenty of room for focus. So I'm not sure what the issue is with your build, but you are the only one that has had this issue??

Is you diode pressed flush? And, have you tried it without the spring?

Also, you may be going past the focal point. It would be easy to do this.

Check to see if you diode is pressed flush, and then try it without the spring and turn the laser on with the lens only half way threaded in, and then focus it.
Jay

P.S. You will be using this lens! ;D You will find out that your Sure spring is still too long, or maybe your diode is not pressed flush...

Edit: I just checked out a Sure module spring and it is a thicker spring (although shorter in length) So when it is fully compressed, it is going to stop your 405-G-1 glass lens mod from being able to thread close enough to the diode. You should not have to cut much off. First try it without the spring. Also, you will find that some Teflon tape around the metal threads will make a nicer fit into the AixiZ module. ;)

Good news. You were correct about the Sure electronics spring, that was the problem. Even though it is shorter I guess it wasn't short enough. Just tried it with no spring and looks great. Also just for reference, I use The Monk's diode pressing tool, which gets the diode in perfectly flush every time :)

thanks for the help Jay. I'll measure it now.

edit: Pretty good results on the 6x
Maximum power w/ acrylic: 196.44mW
Maximum power w/ 405G  : 225.00mW
14.5% increase

Avg power w/ acrylic : 191.89mW
Avg power w/ 405G   : 210.46mW
9.7% increase

I'm happy :) thanks for your work to make these Jay

Re: FS: 405-G-1 Glass Lens Mod-28% Increase vs Aix

I'm glad you got it to focus. :) But there is something wrong with your measurements...

You should get a minimum of 26% increase in power compared to AixiZ acrylic.

What kind of meter do you use? I used to have an optical meter that did not work accurately for 405nm. Do you have a thermal sensor? Or optical?

I use a Andover Holography LPM-1. I believe it is optical. There has been much debate on reading 405nm with this meter as it does not have a setting for 405nm, just 473nm. I've done a lot of research and found a multiplier of 2.58 * the 473nm reading gives an accurate 405nm reading.

This shouldn't matter though as I used the same multiplier for acrylic and glass...

I did the acrylic measurements when I first made the laser so the batteries might be a bit lower. I bet if I charged them I'd get more power out of it. Its not a big deal though.

edit: also, I forgot to mention that these acrylic measurements were taken with the back end of the lens opened up to allow more light through. I'm assuming your 26% was taken without this being done which would be another reason of why I only got ~10% avg power increase.

thanks,
Kendall
 
Re: FS: 405-G-1 Glass Lens Mod-28% Increase vs Aix

Thanks for getting back to me...

I have never built a laser without cutting the back of the AixiZ lens open. All of my comparisons with AixiZ acrylic lenses are with the back opened. (perhaps this could be why some are reporting 30% though)

I had the exact same Andover LPM-1 meter before I got my Coherent PowerMax 5200 with digital read out and PM3 thermal head. The Andover Holography optical meter is a good meter for it's pre-set wavelengths.

But not for measuring 405nm with a multiplier. The inaccuracies are simply multiplied!

A bunch of us passed around the same lasers to compare readings with our meters for blu-ray as well as red. We entered our results in an on-line spread sheet. In the spread sheet, I also entered my measurements with the Andover LPM-1 meter. See the comments as well:
Spread sheet: http://spreadsheets.google.com/ccc?key=pW49OuYfRMm7FXsb9trxWdQ&hl=en

You can be sure that your blu-ray lasers are now putting out at least 26% more power than they were with AixiZ acrylic! (back opened) :)

Re: FS: 405-G-1 Glass Lens Mod-28% Increase vs Aix

Is this going to be an ongoing item???

I'd like to get one, but I'm not in a big hurry as I haven't even put together any of the blu-ray's I have yet.

At this point yes! :)

As long as there are people who what  the modification...

I will keep a few on hand because I could always use them for more of my personal builds. The nice thing is, the 405 lenses are only about 45 minutes away from me, and Will ships them the very next day. (even the same day if I order in the morning) So all I really have to do, is keep the AixiZ glass lenses over stocked.





Hemlock Mike, your 405-G-1 glass lens mod shipped today! (Friday)





kage, same goes for yours!

Please post your observations and comments on the modification in this thread! :)

Re: FS: 405-G-1 Glass Lens Mod-28% Increase vs Aix

I'm probably gonna be getting one in the near future :D
 
Re: FS: 405-G-1 Glass Lens Mod-28% Increase vs Aix

No problem...

Just let me know Spyder!

Re: FS: 405-G-1 Glass Lens Mod-28% Increase vs Aix

I got my lens today and just tried out :D
Wouah, this lens is awesome now my 6x running at 198mA was putting out 320mW (more than 30% avg power increase) :o

Many Thanks Jayrob  ;)
 
Re: FS: 405-G-1 Glass Lens Mod-28% Increase vs Aix

NICE! 8-)

Glad you like the mod! And thanks for posting too! :)

Re: FS: 405-G-1 Glass Lens Mod-28% Increase vs Aix

Sorry i did not have time to test much, and my sf-aw210 order had glitch and never happened, so I'm only re-ordering them today.

You guys know how all our red diodes when reaching best collimation point begin to display line across the dot, right?!

I always wandered why it doesn't happen with violet diodes as they have similar pattern,  and angle of projection.

Well,  this new 405-G-1 lens does the same thing to any of my violet lasers. To red ones, line across is about twice as wide. Diameter of the beam is about half the size if regular glass lens, 2x3mm  versus 4x5mm with cheap glass lens or acrylic. To violet, it creates line which is somewhat separated from the dot but same type. Its much less visible as its very pale and contrast between it and the bright dot is huge for eye to see both easily.

It  has much different focal length which requires different position in front of the diode ( in this case much closer to diode)  which picks up all light from diode and sums it up into collimated beam with artifacts.  I don't think there is way around it, much like trying to get rid of line across red dots.

Someone can better explain optical technicalities step by step which lead to creating the line out of single mode diode pattern projection.

*************

405nm-G-1  is worth every dollar though. It not only lets 28% light out giving you more power per amount of current which spares the diode, but it also spares diode extra heat, and beam backfire into the source which all adds up to longer and healthier life at higher power.

Its nice to see new thinner beam in both red and violet.


************

Here is a photo of two exactly 330mW  before lens diode projections at same distance from wall  (violet 6x  vs. red open can)

Re: FS: 405-G-1 Glass Lens Mod-28% Increase vs Aix

here is same setup but well collimated (red with regular aixiz glass lens, and violet with 405-G-1 lens)

ignore red diode artifacts over 405nm dot
