HELP ME! 505nm Build request!

Hey guys,

I've seen those new 505nm diodes popping up everywhere and $37 for just a diode dosen't sound too bad at all. I do have a request though:

1) Can anyone on the forums help build a laser pointer for me with this diode? Im not aware of how much current it takes etc... but don't really would like this diode pushed for more power honestly. If you could get it to run at what's it's rated that would perfect! :)

2) When it comes to a host, I was thinking of using an eBay pen and just slapping the diode in there, or any other advice you guys might recommend? $30 for 505 is too good to pass up! :)

Thanks!

They are only rated for 30 mW, but can be pushed much higher. I'd probably try to get at least 60 mW, but that's your call. I've been testing the "480nm" diodes for power and wavelength. After that I'll move onto the 505nm diodes. DTR has posted videos of power vs current on both of these diodes on the website about them. Good luck with your build. BTW, you can get that diode much cheaper from the site listed on the thread about them. I believe they are $12.00 for one. :)

Thanks paul! Which site are you referring to? eBay? I checked and they are quoting $40 for them. Regarding the build, I'll most likely buy one of those blank eBay host and put it in there.

I do need someone who is willing to build this laser for me however. I'll supply all the needed parts :)

I'd recommend talking to EP about his little pen build with the copper heat sink. Think they would go great with this diode. Food for thought anyways. Their on his build thread if you wanted to check them out. :)

Thanks Bob! I'll see about sending EP a message regarding building it for me. In the meantime, do these diodes generate a lot of heat? Is there room for it in a pen host? I first need to get the diode, then I'll worry about the rest later :)

The thread is "505nm and 480nm diode RESULTS". You'll have to look from the OP on.

The husky pen lights are great. The power bottom on the back has a semi push for momentary action and regular latching switch. As long as your ok with the front half of the module being the main heatsink. Zero problems from my builds.
EP's work would definitely be a classier host and worth the money of you have it to spend.

I can't answer the heat question. But I'm planning on putting a 515nm @120mw's and a 520nm@120mw's in them. So I'm guessing that they wil produce a lot more heat then the 505 would. I think they should be just fine in that little host. I've got a m462 in one now, and she's just as happy as a bug in a rug. :)

It's just like this one.

Thanks, yeah. I actually was looking at DTR's shop and he has the 505nm diodes listed. Now, which one would I need? I see tons of leads w/ copper module, bare diode, 20mm copper module and all that stuff which dosen't mean a darn thing to me!

I just need something where I can slap in a pen, hook batteries and im done(of course a focused laser is nice too :)). I also see G-2 and 2 Element lens etc?? What does all this mean lol. HALP!

Would this option work for me?

You don't need a 20mm module for any of these diodes. They can be pushed much higher than you think, but the wavelength increases when you do. That is good for the "480nm" diodes as they are really around 473nm to 475nm at 130 mA. They can get to 477nm if pushed to 300 mA. Some may even make it to 478nm. I'll know more about the 505nm diodes tomorrow as that is when I'll start working with the four I have here now.

Okay. I see the $45 option is the 12mm module, which I assume simply means the module is smaller, correct? I am not sure whether or not this comes with a driver as it isn't listed. This is the cheapest option(apart from the bare diode) which is fine for me. Like previously mentioned im not looking to get 100's of mW's out of this, just getting 55mW or 70mW is completely okay with me! I also have the option of either a 2-Element lens or a G-2 lens or no lenses at all?

Which one would be the best for a simple pointer, lens wise?

At that power, the acrylic lens that come free with the module will wok fine. You will need a driver, though. You should be thinking of that at the same time you are looking at other options. You will need to drive it at 170 mA to get 75 mW out. That's a guess as i have only the spec sheet now and will know more tomorrow.

Alright, got it paul! So that's settled. Now, since you mentioned I need a driver, the mean the $45 option dosen't come with anything, just the diode & module. How about the X-Driver option?

W/X-Drive

This one includes a driver correct? So I simply would need a host and that's it correct? :) Thanks for helping me :)

There has to be a typo. Nano or flex drive. 1 cell drivers. Doubt using a buck.

I was thinking the same thing, not sure what's up with that :thinking: A low powered diode like this would normally see a boost driver.

Thanks Bob for the referral :D Like Alex said, looks like we've got a decent build plan going!
