Someone to repair my 100mw green lazerer classic

Hi.

So I'v had a 100mw green classic for a while now, about 2-3months, and a few weeks back,the dot got really dirty, something on the lens, it had a awful lot of spatter around it. I couldnt figure out the problem, so I opened the top lens cap, revealing the assembly inside. There was a white lens on top of the C shape diode thingy (collimator lens?), I tried to clean it but it didn't do anything, so I took it off assembly and cleaned the underside, bam, the dot was clean , but it was now not connected to the assembly, and I have found it almost impossible since then to put it back on accurately so the beam is aligned. also, I don't have any glue that I could use, superglue releases fumes or something so I cant use that.

So what I need is someone preferably in the UK that I can send my laser off to and they can re glue/attach/align either the same collimator lens or a replacement one. I dont know much they cost, but if anyone is willing to do this for a reasonable price, shoot me a pm and we can work something out.

I would really prefer someone in the UK, mostly due to the fact I dont want to wait like 2months for the whole shipping process etc.

Thank you

My method for realigning the optics in green lasers is this:

0. Clean all optics carefully and minimize the amount of dust in your work area and make sure you have removed all chemical residue and dust from optics.
1. Reduce power to pump diode so that the crystal set just begins to lase.
2. Place the module in a heatsink and then in a vice to keep it stable.
3. Position the module vertically so the beam is projected directly upwards.
4. With the module in place, carefully place the lens on top of the crystal set as close to centered as possible.
5. Carefully replace the tube that houses the collimator lens (this lens is usually already centered).
6. If the beam is off-center with the collimator, use a toothpick or other fine tipped object to gently push the lens into place. If the lens shoots off to the left, push the lens slightly more from the right and vice versa.
7. Repeat 5-6 until it is as perfect as you can get it.
8. Mix some 5 minute epoxy. The longer it takes to dry, the better. Using a fine tipped object, put 3 small dabs of epoxy around the lens to adhere it to the mount or top of the crystal set. Be careful to move the lens as little as possible while you apply the epoxy.
9. With the epoxy applied, repeat steps 5-6 again to ensure the lens is centered.
10. Turn off power to the module and let the epoxy set for a few minutes. Cover the module carefully (do not touch the lens!) to prevent dust settling on the lens.
11. Replace the collimator lens again to make sure nothing has changed. If the lens is slightly out of alignment, make final adjustments (step 5-6).
12. Once the epoxy is fully dry (give it at least an hour or two to be sure), apply a little bit more to ensure a strong bond. Once it dries, double check that is is centered and you are good to go!

Edit: Be sure to use goggles. Sometimes when adjusting the lens, the beam can shoot off at an angle toward your face. Even with reduced power and a highly divergent beam, a bright flash of green can screw up your vision for a few minutes and possibly cause damage!

I have fixed an old pioneer 6 disc cd player for my Dad by using a special kind of super glue readily available at model building stores. It does cost around $10 (usd), but it worked like a charm.

I tried to find a link to somewhere in the UK you could buy the glue but to no avil... you'll just have to ring or go to your closest hobby/craft/model store.

The lens had somehow came unglued from the sled and so I took it apart because I heard a rattling and I knew that must have been the problem. I then got my dads super special superglue and used a toothpick to apply it to the lens. It only took 3 teeny little dabs though so dont go overboard. It now plays Cd's like a champ! Epoxy may work as well but I have not used it before for this application so i cannot speak as to it's efficacy.

*disclaimer, I cannot guarantee that this will not "haze" the type of lens you are working with, but since it worked for another laser application I thought I'd toss it out there.

I also just found this thread Link: http:/http://laserpointerforums.com/f42/lens-glue-27710.html/

Good Luck!!!
