Hey LPF! Boy, have I been away from building lasers for a bit. My time has been focused on a mix of grades, hobbyist bushcrafting, and building a real nice flashlight for my brother. Nice ol' graduation present collaboration with me and my buddy over at CPF.
ANYWAY! Now onto the obvious crux of this thread, my new <5mW 635nm Chrome Leadlight.
I've always wanted a 635nm laser and didn't really want one up in the +100mW range. My first idea was the obvious... buy a diode and make a driver. But then I remembered seeing these cheap "5mW" 635nm line modules on fleebay. They ran off of a 3V driver and you can just remove the diffraction grating to get a clean dot. So I put it together into a shiny ol' Chrome Leadlight.
I don't really call this a build because I really only soldered two wires and used a pre-assembled module. I definitely enjoy doing a build from the ground up much more. But here's the dot. Single mode and just radiating with 635nm goodness
One thing noteworthy about this is that the module is case positive and so i had to use a case positive set up. Which is really not my favored case-setup, but I don't really mind that much. Like my other Leadlight build using a PHR-805, I had to use a magnet in order to have sufficient contact between the two AAAs and the spring of the switch board and the tail cap.
My DIY LPM only picks it up as 3-4mW and its brighter than all my 650nm pointers. So those two facts give me peace of mind that it indeed is 635nm. Plus I can definitely see the difference between the two wavelengths.
That's it for my build! Thanks for checking it out. I'd recommend a build like this for someone trying to get their feet wet with lasers who wants something a little more than 650nm but doesn't want a ton of power. And hey, its a nice addition to anyone's laser collection
I don't see myself dabbling too much in high power 635nm lasers so I think this will be my only 635nm laser for now at least.
And of course.....
BEAMSHOTS!
Thanks for taking the time to check out my thread I really appreciate it! If anyone has any questions regarding how to put together a leadlight, I can now say I have experience in both adjustable focus and fixed focus builds. I'm not the best person to ask as there are much much much much MUCH better builders than me, but I will answer any question to the best of my ability and if I don't know the answer, I'll try to point you in the right direction.
Check out some of my other builds! They're much more interesting than this. The link to them is in my signature.
Okay I'm rambling.
Keep on building!
