Thanks all for your knowledge!! Anyone else tested first contact? Because if its a way to make it as clean as possible in just one simple step without any risk, i will definetely give it a try!! No need to worry about damaging the lens or the coating and simple to use, that's perfect for me :)...

I also saw that when searching for cleaning methods, but i will be more confident with First contact!

I think it's far too aggressive for sensible optics, the ar coating will not like it i think. Thanks for your instructive review!! First contact seems to be very effective, it seems lot of people love this method here but i needed a precise and comparative review as yours! :) I tried q-tips...

Hi!! It seems to be a noob question but i already searched so much about that, and there's so much differents ways to do it, like one recommended by one person disaproved by another... etc, so i need some clear and good reviews and advices. If it's just some dust an air blower cleaner is the...

Thanks Blord you're more than a great builder! Thanks for your support! Pm sent!

I think i would definetely try, i just want to be sure there will be no damage to the diode. I wanna buy the complete barrel with focus ring, so i just will have to swap it and not disassembly the barrel to swap lenses. Will you sell me a complete one with focus adapter?

Thanks for the advice! For the dot quality the 3 element is still the better? I think so. I don't know what to do exactly... ;-)

Thanks for the confirmation!! With a g-9 lens there will be a difference in the dot? I didn't found a photo here.

Hi! I just wish to have some technical reviews about putting a 3 element lens on a 2.5w 445 diode. I want to have a more squarish dot and with less spash sometimes when i have long distance pointing needs. I don't care so much about the loss of power, i will not use the 3 element all the time...

I will take some today. I shine the laser in front of the mirro system just a bit in upward direction, to let the reflected beam shine upward to the first beam. I didn't masked the angles of the mirror do you think that's the problem?

Oupss didn't looked at the date... I already pmed him, i posted just if someone else would know where to find it! Sorry to bring back the dead topic :-)

Hi! Where can i find this lens? Thanks

Hi all! I tried the liquid sky effect with the computer fan and a mirror glued paralel to the axle. But i can't make it work, the problem is that doesn't create just a scanned beam in front of it on just a little angle as its supposed to do, but a beam at 180° around the mirror and also a part...

Re: For sale: NEW 1W-2.2W 445nm 501B lasers with copper heatsink from $100 Je suis français aussi! Je lui en ai pris un il y a à peu près une semaine, c'est tout simplement une bête de puissance! Dans la version 2.2+w c'est une diode 9mm donc différente de la m140 dans les autres versions...

Re: For sale: NEW 1W-2.2W 445nm 501B lasers with copper heatsink from $100 No i didn't tested in the wrong direction, i thought to do that just to test if the sticker is in the wrong direction, but not tested because i'm not sure about the polarity protection. If you can i prefer a refund...

Re: For sale: NEW 1W-2.2W 445nm 501B lasers with copper heatsink from $100 I don't have one for the moment, i lended it to a friend :-( It's the single one, i would need a double one one day, it's annoying to charge batteries one by one :-) Is there a reverse polarity protection on this one...

Re: For sale: NEW 1W-2.2W 445nm 501B lasers with copper heatsink from $100 Only one flaw, the charger is not working, i used mine to charge the batteries and later i just tested the one you have send me, when i put the battery in, no reaction of the led and i confirm it's not charging. I...

Re: For sale: NEW 1W-2.2W 445nm 501B lasers with copper heatsink from $100 Just received it! Simply one word, wooooow! What a beauty! Charging the batteries, just made a test before but i think it's far away from full power.. Can we charge both batteries at the same on the charger by aligning...

Re: For sale: NEW 1W-2.2W 445nm 501B lasers with copper heatsink from $100 Waiting for mine, perhaps today it will arrive! I hope :yh: Why not shining it at the sky? That's so great a beautifull beam in the night sky! You took which version? Enjoy it and stay safe! :beer:

Re: For sale: NEW 1W-2.2W 445nm 501B lasers with copper heatsink from $100 Just to say my 2.2+w shipped on the 7 is already in France i will have it tomorrow!! What a quick shipping! Will make a review as soon as i have it! To wait i'm on admiration on this great Lpm graph :-) Thanks again Blord!
