Fuzzy beam on 6x?

Spyderz20x6 · Mar 12, 2009

Well, it started like this:

I built a 6x pocket mini, and accidentely scratched the lens. It was ouputting 172mW.
So, i bought a new lens, and then it was outputting 190mW...
As i love to tamper with everything, i unscrewed the lens and decided to clean the diode window with a q-tip and rubbing alcohol.
Now, the dot is fuzzy and it is outputting 174mW.
I tried cleaning it again, and it only made the fuzz worse...

What do I do to make the fuzz go away and make the output 190mW again?
In other words, how do i fix this?

if u wanna take a chance..

andif you have a dremel... cutting disc for the dremel.. and a steady hand you could just cut off the top where the window is attached..

i did it with my red laser i rebuild.. u just need to make sure no pieces of metal get into it

405nM diodes are sealed under an inert gas.
If you expose the Gallium Nitride to oxygen, it will degrade the chip and eventually kill it...

It is likely that you scratched the window and it is irreparable. If you really want to save it you could try rinsing the diode by pouring some alcohol in and then some distilled water to see if there was just a few fibers dried onto the diode (By now such fibers would probbably have been burnt onto the window of the diode).

That's pretty much it.

Crap :-[

Should i mix the water with the alcohol?
How do i remove it? Do i wait for it to dry, or wipe it off?

I would try using a dropper to drip/spray enough alcohol to rinse the diode window and then shake it out a bit/dry it with compressed air. After that, remove any possible residue the alcohol has left behind by doing the same with distilled water. One or two repetitions of that may clean up the window.

Well, i put a dab of rubbing alcohol on, and managed to raise the power to 180mW.
However, i am still not happy with the beam...
Would a LensPen do the trick?

There are no fibers burnt to the window...

Well at this point you might as well try what you can.

Yea, i guess...

As amateur as it sounds... I have had good results with windex and super clean q-tips. The trick is to not touch the glass with the same point of the q-tip twice. Put a small amount of the cleaner on the q-tip, rub it with one stroke lift , rotate the q-tip to another fresh spot and repeat. Then do the same with the dry side, avoid more than a single stroke with the same section of cotton.

When you are done view the diode under good lighting on an angle and look for any spots, streaks and cotton fibers.

Do not touch the ends of the fresh q-tip or you will be adding the oils from your skin into the equation.

I got thermal paste on one of mine and went through 4-5 q-tips getting it completely off

Thanks

I'll go try that!

No problem

I used to use alcohol strictly, but try cleaning a window or mirrior with alcohol... :-? Streak city

Yea, i realized that alcohol only makes streaks :-/

I have no idea, is it possible that it may be a plastic lens? I have never taken one apart, I would assume glass but is is really? :-/

Heruursciences.
I have decanned a few PHRs and a 4x, and they only survived a couple of hours.

Fuzzy beam on 6x?
