Thanks a lot for your reply, I understand now how is it important to have the correct wavelenght lens for a diode. I wasn't thinking that there is huge difference between these diode (simple to double...). So what is its nominal output ? 1W ? I think I will make my custom hostmade with copper...

Thanks (again) for your answers I understand better now... And for finish with lenses is there a big if we use a different wavelenght lens compared to a lens with the adequate wavelenght for a diode(with of course the same number of element) ? I see somewhere that the M140 diode are sell for...

Thanks that's help me a lot. WTF ? we can see on the graphe that an aixiz acrylic lens is as performed as a glass lens ? But we can't use it for high power, is that correct ? WTF(2)?we can see on the grphic that the wavelenght for glass lenses have no impact on the ouput, and a 650nm is more...

Thanks a lot for your help You are right for the LM317 and of course with a heathsink ^^ Is the aixiz's module suffisant to use as an heathsink ? So if understand we use for long distance glass lens and for short distance Gx lens. What is for you a short distance and a long distance ? Maybe...

My driver is a LM317 (in TO-220) powered by 2 li-ion. You can check on youtube there are a lot of similary videos so I don't think there are all fakes. What is the gain for a G2 lense compared to glass ? and G1 ? So I think I'm interrested for the M140 diode, because it's cheaper and have a...

Thanks for your quick answer guys (I haven't the time to answer you this 2 weeks ago =( ) In fact I just want to light a cigarette or a wick; I don't want to burn plastic or other things like that... So how can you explain that a 135mW 658nm laser can burn a match and a 200mW 658nm laser (which...

Hello thanks for your reply Are you sure ? because I see some videos on youtube and they burn things with a >100mW diode laser... Are they a special lens ? Thnaks for all

So I received yesterday my red focus lens and my module, so I pressed the diode with my etau ith a socket (don't remember size and type) and after I adjust my driver to the max current that my diode can support and finally I adjust the distance between the focus lense and the diode to have a...

Yeah I'm consicent that this build is not a toy. You were very helpful for me and I don't know what will I do without you...

OK no problem I will do for you =) however I'm from france so it will take a while before I receive parts....

Thanks for your reply, Ah I haven't see that thanks I will buy to him even if it's a little more exepnsive...

Ah ok I understand now for the shape lens so for my usage it's useless, ok for the focus lens I think I will buy a glass 3 element AR 650nm lens because G-1 is too expensive ;p When I speak about aixiz module I referer to the official dealer (which is aixiz) and I was thinking that you already...

Hi, Thanks for your reply I'm not sure you read me correctly; I want to know what I get if I buy a Aixiz module not what number correspond to. OK thank for your tutorial, I have a pressed so it will easy (I hope). OK for the line generator I understand so this aixy module doesn't have a line...

Up please. I priomise that was my last questions ;p

Thanks for your reply with all pics ;) I understand a lot of things however I don't understand (again) how can I take the lens which is in a piece of metal... Ah maybe there is finally 2 lens ? one shape lens and a focus lens Is the shape lens obligatory ? is it possible to have one with just a...

Thanks a lot for your reply, Yes of course I have a home made module but no heatsink for it because it can delive 1.5A without it and I just take (max) 0.25A. I don't understand something you said that I have to put the lens in the metal rings however can we remove the lens from its socket...

Thanks, thanks and thanks a lot, I learn a lot with all your explications... I think I will choose the lens from aixiz because they sell 9mm Cross Hair Lens for 12mm Casing and if I buy this it will be more easy for me to fit the lens in my custom casing... But I have a few questions on it...

Up please =)

Thanks for your reply, My diode is the same as this link : 658nm 200mW High Power Laser Diode TO 18 Package [JG27] So it's a simple diode What the difference between acrylic and glass lens ? the price ? Is acrylic made for high powered diode ? Can you explain to me how a lens is made for a...

Ah okay, I must adjust the distance between the diode and the lens... What do you mean by "if it don't work ?", if I take a lens from a cheaper chinese laser, it will work, isn't it ? Sorry I don't understand (too) "weird artifacts" Instead of buying one cheaper laser, where can I find a lens...
