How to get the diode out of this host?

micksterbs · Sep 10, 2010

Hi y'all.

Got this "300mW" green thing (real power unknown, til my Kenometer arrives!) and want to remove the diode to use it in to a 7-colour build I'm embarking on.

Trouble is I can't see how to get it out :-/

The front unscrews and the lens assembly comes off, and the diode remains in the body. Does the body unscrew at the taper maybe? I can't shift it. Or is it glued in?

I've tracked the manufacturer/distributor down to a Chinese company called "Anyang Dinghui Electronic Technology Co.Ltd.". Which is helpful.

Pics below.

Cheers!

need more photos from different angles, macro's if you can.

Here you go. I really can't work this out. See the notch in the threaded part of the bit holding the diode? There are two of them, opposite, which look like a way of unscrewing the thing, but firstly, you can't get at them properly because the hole's too small, and secondly, even if you could unscrew it, it's too big to fit through the hole. Could it screw out backwards maybe, into the battery compartment? There's bugger all down there except a black insulating washer that looks a bit like felt, and the battery spring. It's very difficult to photograph down there!

Why cannibalize a perfectly good laser, when you can just buy a cheap green module? Even if you didnt care about the laser, you could sell it, make some money, and get a module.

micksterbs · Sep 10, 2010

It just struck me as the most cost effective and hassle-free way. Do you know of a good source of cheap 300mW-ish green diodes, preferably in the UK? I'll check out some prices.

Here is one from O-Like.

High power 300mW green laser module/IR filtered [OLHGLM250] - $225.00 : Welcome to O-Like.com, Your source for laser products

I'm pretty sure you dont need anything near 300mW to make a decent 7 color laser.

T_J is right, people are building these things with 50mW-70mW 532nm modules, remember the the human eye is very sensitive to 532nm light.

If that host is anything like the one I got from DX some time back, and it looks to be..
All I can say is good luck. Those are epoxied to death, and are quite difficult to break down.

If damage of the internals is not a concern, it can be done. Though I wouldnt expect
to get the internals out, without killing them in the process.

Proceed slowly and try not to scratch the outside...

Just so you dont destroy a perfectly good laser that diode in that host is a 808nm IR diode. I wouldent mess with it. I have never taken those kind of lasers apart but maybe it unscrews from the back. It looks as there's threads on the front. I can't tell from the photos but is there green epoxy in there or is that from the camera. Perhaps someone has one like yours and can help but that's just my 2 cents.

Anyhow hope you can get your module out without breaking your laser.

micksterbs · Sep 10, 2010

I'm pairing it with a 500mW 638nm, and an ex-Casio 445nm running at well under its max rating. Is there a formula for working out what relative powers are required for a nice white, given the wavelengths? If I can save the pointer and use a lower powered green, that'd be great.

This is looking less and less sensible

Thanks for your input everyone. This place is amazing.

You want a program called "Chroma"

If you don't want to download it, here is the perfect white balance with 500mw bright red according to it:

500mW 638nm
350mW 532nm
300mW 447nm

300mW green is actually a bit low, and I kind of doubt your green laser outputs the whole 300mW. Then again, you don't have to run the red diode at max

Could you cut those figures in half/quarters and still work?

I could...

Ultimately it'll be decided by budget. I'll prolly have to start low, and upgrade the green when I can afford it.

Don't take this the wrong way Tech_Junkie but it's quite difficult to take you seriously with that avatar

I like it that way, LOL. I'm a born and raised ballbuster, and am always cracking jokes. Like Curly...:eg:

Just downloaded Chroma.... good grief! Awesome.
