New 9mm 445 diodes

There is no need for the spacer. With his Lens Nuts you just keep screwing down until it holds the lens tight.


THe Len Nut is threaded all the way down on the inside. SO when you keep screwing you will eventually get to the Lens and it will hold it in place. Just be-carefully not to damage the lens when screwing.:beer:

Hmmm. That pic is lacking some detail that would clear it up for part timers like myself. These are my first lens to assemble myself so I just want to make sure it's right.

Which lens holder do you have?
If you have the golden one it is different from the picture from Blord

You just unscrew the nut
drop the lens in
make sure the flat part of the lens is at the bottom
(curved part faces the inside of the holder)
then screw the nut back in until the lens is secure

This works on the newer lenses only IIRC. On the older ones the retaining ring
wont catch the threads and needs to be drilled to accommodate the thickness of the lens.

You should put in like this ,

They are not Aixiz barrels. He has a lens barrel from dave over @ PL. No modification needed for any that I have used including the different shaped 650-G-1/2's.:beer:



Anyway the nice little diagram shown above by justinjja is correct. Enjoy.:beer:

Okay, maybe I am doing something wrong but I can't get these to focus to infinity with a G2 lens. It is like a flashlight, and I keep screwing the lens it, and when it gets to the end it still isn't properly focused

Works fine with an A140, but I can't seem to get the 9mm diodes to focus.

i've been reading thought this thread and i can't believe that lazeerer get's 3.4W out of these things and has another one with the same efficiency! It would be so crazy if JLSE did the same magic with these two diodes as with his 3.5W dual build. Then it would go up to 6W+ :drool: Then you might want to wear to laser safety goggles on top of each other Are the optics for such a thing still good? Or do they cannot handle such powah?

Anyway i was just drooling away here on this thread :tinfoil: Sorry for the offtopic guys...

What module are you using ? Some modules are too long and the lens wouldn't get close enough to focus to infinity.
Get the focus ring off and try again.

I'm using the 9mm diode module from the GB, it's one of the extended ones if that makes a difference, but there is no focus adapter. This is screwed in as far as it can go. Could it be the lens barrel isn't getting the lens close enough to the diode?

The last time I tried a G-2 in my standard retainer was with that rayfoss modules in the op before the copper ones came in and I remember having issues but I though it was the module then. It is possible that barrel does not allow the lens to get close enough.

I have been using the 9mm lens with one of Dave's barrels with these diodes. I will have to try a G-2 as soon as I get some more modules in. Dave's barrels do have the lens sit closer to the diode and the 9mm can is taller so that could be throwing it off.

I never seen something like this. My LPM don't go higher than 2Watt so I use the blue filter method to extend the range.

1.6A with filter measured 1890mW so actual power is 1890/.86= 2,198mW
1.7A with filter already beyond 2 Watt so actually power is >2325mW !
I need more filters to block the beam

You need new LPM or upgrade it.

filters may work better for you than the one you already have, they reduce the power by a greater factor.

well im in a bit of a predicament.... I guess when I was pressing the diode into its housing I must have done something and cracked the lens that is in the diode itself... Is this fixable or is the diode trash? I fished the pieces out through the hole in the front very carefully and the diode still lights up fine but does not seem to have any power. I dunno if it was like this before I started or not because I didn't inspect it before I got started. I am always very careful with this stuff but I know it is all very fragile. I am taking the blame here but am hoping that that lens is replaceable if I send it to someone... :cryyy:

The reason you cannot get it to focus is the lens is Not sitting close enough to the Bottom of the lens nut there for when you screw your lens nut in as deep it will go its still not close enough.

If the Lens does not sit deep enough into the lens Nut you will not get it to focus. Which is what is happening to you.

I found this issue much more with the Shorter FL of these Lenses from the Projector and when using these 9mm diodes as the can of the diode sticks out more so there is even a far less gap you can have when you are making the lens nut.

:beer:

Edit:

DKlaser@ probably when you where fishing out the little pieces of glass you removed some of the bonding wires or damaged the Facet or something. Sound to me like its Toast if your getting very little light out of it at a higher currant.

Thanks! :beer: I bought some different lens barrels that should lower the lens closer to the diode.

Damn that's a tough one to swallow especially for a brand new diode with no time on it.
