The only lenses i have are these alleged collimating lenses. Ill see if i can rig something up tonight. Ive been using my custom machined laser host to test the lenses, and its difficult to adjust the focus, as i have to pull the press fit nose off it and pull the laser out, then adjust it, and...

I have tried adjusting the distance between the diode and the lense, but with the new lense, it moves the focal point from about 1" from the lense to about 6". I might just be better off buying new lasers and starting over... im a complete noob with optics, and have no idea what to do to fix...

DPSS 532nm green. i bought a blue-ish purple (forget the wavelength) one off banggood, and its completely different, and has the same focusing issues. i cant get a flat beam output from it... it has a focal point, but i can adjust it to about 6ft out. when i point it at my roof, its a 1mm dot...

i dont want to risk damaging the un-ruined lenses by removing one, and for some reason i cannot find the 5 that i already removed. the replacements are flat and convex, and it makes no difference weather i put them in convex side out or flat side out... the original ones appear to be flat on...

so these are not collimating lenses? they are flat on one side, and convex on the other... maybe i have it in backwards... ill try that... i had a REALLY close look at them... i thought they were convex on both sides... - - Edit - - putting the lense in convex side down makes no difference.

So i learned the hard way that my collimating lenses are made of plastic, and that crazy glue, or ca melts them... i ordered some replacement ones and they dont do what i was expecting... i was expecting to have a straight beam like i had before, but with these new lenses i get a focal point...

that makes a lot of sense. maybe id best stick to a dremel cnc or something instead of a lser cnc haha! oh well... ive checked out a couple other member builds, ill check some more out though, im definitely up for inspiration :)

Yea, its on my 'once i get the lathe making money, ill buy it' list haha! My first real experience with a laser would have to be at a manufacturing plant. They had one of i think 5 or 6 high powered laser pipe cutters in Canada (if i remember correctly). Id enter the parts, load the pipes and...

interesting... a little more complex than i had originally thought, but not too bad... am i going to need a variable power supply to figure out forward voltage? because i have no idea... i think there are too many unknowns to figure out this equation... i dont know the forward voltage, i have...

i am thoroughly enjoying lasers right now. honestly though, im kind of questioning what to do with them... they are cool to have, but for me, personally, they do not serve a purpose haha! i have no use for them... what do you do with your lasers? on the other hand, im also more of a 'enjoy the...

Nice. So how do your hosts come apart? Threaded or press fit? Once i get a proper tool for doing inside threads, ill be able to thread stuff. But for now, this one is press fit with some snap rings i made :) Cheers!

10440 and 14500; are those battery sizes? i have a lot of 18650's so that's what i designed my housing around. i harvest 18650's out of drill packs, laptop packs, anything i can haha! thats what i do. the Wife and I go down when she has a couple days off in a row, we spend 2 days there, and i...

its fun haha! out of rep? the switches that were on these lasers were those little 4 leg SMD miniswitches... they dont handle much current, so i used a switch with bigger contacts, and it works just fine. still would like to find a better solution, but honestly, i think im going to have to...

Thanks man! yea, the last time i used the lathe, i turned down some hubs for my 1985 toyota pickup. i needed to fit rotors over the hubs, instead of bolting the rotors to the back of the hubs, so i turned the little ear tabs down... that was... oh jeeze... like 5 or 6 years ago... last week i...

ive never made a portable laser host before :) the first run of parts i actually manufactured myself were Medusa's heat sinks. they fit lasers inside them. but this is a whole new beast haha! had to incorporate a battery area, and have it separate from the laser area, and have enough space...
