1 to 2 inches? Is that all without the beam extender?For very close burning.....say 1 to 2 inches, you don't use a beam expander. You can simply focus the laser using the collimating lens to the smallest point at these distances. You will no longer have a beam, per se, but a tiny dot of power density. It is more like using a magnifying glass and the sun to burn something. There will only be a point where you will be able to burn at and if you move toward or away from that point you will no longer be able to light a match or burn some black plastic.
Yes sir....two new members indeed got duped. They lied about the wavelength and they lied about the output power and my measurements are traceable all the way to N.I.S.T something I doubt you can say about the Chinese quality system. Finding this forums was easy enough...just typed in Aluminux Laser and this thread and forums was the first listed after the sales sites...of course. I thought it was funny that right after the measurements were complete....it broke. I tried to take the unit apart and repair it but the main laser housing was thread locked into place so....I file 13'd it. It was a rather nice housing though...looks like CNC work. It is nice to be back posting on a forums. I have not really been active in forums since I modded IsoHunt and Administrated TorrentBox. But once they shut down, I sort went into just trolling the disqus boards on news sites. So far the TorchPro has answered every email I have sent them so it will be interesting to see how they respond to my warranty or replacement request. I did not tell them it broke yet but I sent them an email detailing the misrepresentation, which probably means further communication from them will halt. So the Laser fire starter was a bust so I decided to go with an equally impressive piece of technology....a lighter. ....now to go shop for an inverter.Unfortunately Len it's deals like this that bring newbies here for answers and comfort.
I also don't see how new members can find this forum easily, unless i'm missing something?
Oh I came ever so close to buying from laserpointerpro and other scammers, I just lucked out and never pulled the trigger.
So i'm right that 2 new member's bought to what they thought was a blue laser and got a green one?
I am curious if a budget minded hand held laser capable of igniting kindling is even possible? Perhaps a PM is in order? Thanks for tossing some possibilities my way Lifetime17Hi, No hijacking here all is good , I have LPM'ed lasers for many folks to see what they really bought. So I can help you out to if you like.
Hey Ponz...I referred to you as a new member in another post....it would seem you are not....my bad.Question?
Is a beam expander for 'near' burning? What are reasonable burning distance with/without a beam expander? I'm looking at a 7 watt blue unit.
Also - what is meant by single or multi operational modes?
Thanks in advance,
And the price range is within my budget. I am definitely PM'ing you to dial in what I actually need. Thanks again Lifetime17Hi Ponz,
Jet lasers are are a great company yes to order from , I think Hak is an affiliate with them here in the states email him greta guy to deal with if you go with Jet lasers.
Also if you go for the 7W 450 laser you can get as an option their 10X Beam expander that would work well at distances.
Some time ago I made for a customer a custom NUBM44 build with a 10X BE and I tested it on a black tee shirt at 32 ft. burned a hole through no problem.

I watched this video yesterday. How difficult would it be for someone like me with poor soldering skills to get some of the equipment needed, here, from forum members with a little tutelage?
