I need help on my 50 mw green laser

[hotsh0tskill]

Hi i bought this
50mW Green Laser Diode Module Industrial DIY for Kit - eBay (item 320461204424 end time Jan-10-10 03:12:44 PST)

and it says they dont come with lenses -_-
Now where do i buy lenses for that? otherwise it will be like a flashlight and it wont be a beam. please help :tired:

this is what he said to me:
"Yes, it shoots out a beam. If you wish to adjust the focal point of the beam you can use a lens, otherwise the beam "spreads out". At 10ft the dot is around 18mm in size."

Dont panic!
It will be just fine, just connect your battery with the negative side to the spring and the positive side to the case and you will have one very large smile on your face!!

Be carefull and watch your eyes with this beam, its a blinder!

But i emailed that person and he said it does not come with lenses. Only with the driver and diode with housing...

Jaycey, what are you talking about? The laser is missing a lens.

You would have to buy a set of collimating lenses and glue them in place. I think novalasers.net sells them, but it would be easier just to get another module. These are great: 40~50mW Green laser module£­>5¡«500mW green laser module£­>Laser&lighting products£­>www.0-like.com

Also, if you do go that way, you could remove the crystals from the first module and put it in an AxiZ module for a high power IR laser.

You should not make duplicate posts on this forum. I've found 2 so far.

sorry i didnt know i was repeating

Looks like a standard 12mm module to me, im sure there's plenty of ppl here with dead ones that will unscrew and send you the lens assembly...if it needs it

 

[hotsh0tskill]

ya but who? do i just post it on the forum? and how wuts the distance between the diode and the lens?

what i already bought it... the one you sent me is cool but i already bought the other one... can you trade it with me? il give you like 5$ extra

 

[hotsh0tskill]

and also can i use this?
AR coated glass lens for laser focusing modules(red/635-670nm) [LENS2] - $5.49 : Modwerx Shop
its for focusing Red but green works right?
or should i get this?

What I meant was, you will most likely end up having to buy a second one. If you can find optics, it would be great, but I don't think it would be easy. And no, I don't have one.

Also, the two you posted are for red lasers.

what is the difference? why cant i use red laser for green focusing?

No, they are two completely different wavelengths. Green is created through DPSS alignment, red is directly from the diode. Green requires a special pair of different optics.

So a green laser uses a different collimator lens? I though it was just a glass lens, but then again, I think my green lasers have a coated lens, which may not allow red light through too well.

But aixiz told me this might work: AixiZ
And what would happen if i were to put the "red" lens on a green laser module, will it burn out? Block it? what?

It HAS lenses already, just not focusable lenses
