Hi
I want to build a red laser with LPC-826 laser diode.
I already have a standard focusable housing from deal extreme like this: Red Laser Module - Focusable Dot (3.5V~4.5V 11.89mm 5mW) - Free Shipping - DealExtreme

Is that compatible with the diode?
I know that need a heat sink for continuous operation at full power.

Any suggestion?
The diode requires a lot of current, what driver is best? Is LM317 costant current driver sufficient?

Thanks!

you would need a 5.6mm module like THIS or THIS

IMO the first link is a way better deal and DTR is a great guy

That module will work with your diode (so far as I know)

This is a little more than the module you linked, but it's copper and will save you the trouble of removing the diode from the other module.
Copper Module for 5.6mm Diodes - $4.50 : Mohgasm LLC, Have you experienced one lately?

An LM317 will be just fine to power this driver, you will need to heatsink it for continuous operation though.
You can buy this if you want a (similar) linear driver pre-built.
Mohgasm Linear Driver - $6.99 : Mohgasm LLC, Have you experienced one lately?

For a heatsink that can provide continuous operation you can buy 12mm CNC rail mounts on ebay and add an Aluminium heatsink onto those, or contact a machinist here like FlamingPyro/Jeff and he can custom make you a heatsink.

You can get the diode, driver, module, and host ALL from Cajun Lasers and cut down on the cost. Beware of impulse shopping though :whistle:

I have used that module before and it fits a LPC-826 perfect. It's not really hard to get the other diode out - just take a screwdriver and push it out. :)

Thanks all for replies.

Interesting but the shippings costs are 10$.
There is also a 300 mW 650 nm laser diode already mounted on axis copper module for 21$, but with SS i'll pay about 30 $

If i buy only the copper module without lens and housing i can fit it on my DX module? is that compatible?
Maybe it's better if i buy entire new housing mmmh

This is very interesting... this site can provide me the diode, the housing and driver at interesting prices.
With 15$ i can get diode and housing... but the housing it isnt copper :\

The drivers listed are not dimmable right? I need a dimmable driver

edit: very cool idea use CNC mounts for heatsinking! They will be also useful to fix the laser module.
I found this: http://www.ebay.it/itm/2-12mm-Beari...300?pt=LH_DefaultDomain_0&hash=item27cdce3ebc

Yes it is compatible. I have used a Mohgasm copper module with the lens from the module u linked from DX and it fit perfectly. :)

What is the shpping costs on Mohgasm? cannot find any info on shipping costs...
if it is low i can buy this for 4-5 $ and laser diode on ebay with free shippings, so i can build the full laser module with < 15 $... not bad

As mentioned, DTR is a safe bet when shopping for diodes. On the other hand, my experience with hightechdealz was more than satisfactory.

Question: My red build uses an LPC-826 from HTD but I was wondering, which diode does DTR sell in 650nm? I don't believe he calls it an LPC-826

You could buy this lens instead and get a 3-element lens and a spring (not sure if there are springs included in the one you linked):
- DIY Laser Module Host for TO18 5 6mm Laser Diode w H 3 Elements Glass 445nm Lens | eBay

The other things look good. I tried that driver before and it worked fine. Also if you wan't to know - a ¼ turn on the pot is a 20% increase in current (100 mA).

I have already a standard module with acrilic focusable lens, spring ecc.
The module you linked it's good but has 445 nm coated lens... i think it isnt optimal for a 650 nm laser, am i right?

What's the difference between 3 elements and 2 elements glass lens groups?

Here it is with 635 coating :)

I don't know much about the lens you linked. Hopefully someone here does, or you could try to contact the seller and hope he's a legit man who doesn't say crap just to get a sale.

Done. I bought laser diode, laser module with lens and heat sink.
I think i'll build driver from myself.

Any suggestion for mounting the diode?
Is the copper module necessary? if i mount the heat sink on standard module will it be ok?

I'll update the topic when i'll receive the items (about 1 month i think... shippings from china)
