Great, Thanks for your effort, I've added to your rep power ;) It may be surprising but it was pretty dificult to find this info on the web. Nowhere to be found!

Thanks for the effort ped! Is the distortion on the image of the green line caused by the camera? Or is it not a clear line in real life?

OK, thanks everybody!

I see, But if I could break the epoxy bond, turning the lens would focus the laser right?

I'd like to know if you, or anyone else, is/are sure that line lenses like these: will work for different wavelenghts? Because some sellers claim they're for 655nm, and some don't list any wavelength at all. But ofcourse the sellers that do list a wavelength might not know wether or not they...

Hi everybody, look at the pictures of this 532nm 50mW laser: If I'd turn the lens that's threaded into the housing, I'd be adjusting the focus right?

That would be great! I'm not scared of a little modification. Are you sure those kind of lenses work for all wavelengths?

And does anyone know of a store where I can find line generator lenses for 532nm lasers? Thanks

Hi everybody, I want a green line laser, it has to be clearly visible with a camera, so I was thinking 50mW. I'd like to DIY one, but I have a few questions on that. Can you just glue/mount a line grating lens (like this one: Line lens 60 degree for AixiZ 12X30mm laser modules - eBay (item...

What components would you use to make a 50mW green line laser?

I see, What does a host actually do? (why do I need it) The module I've shown (the link to ebay) already has the driver and laser diode. Right? The laser will be mounted on a machine, so it doesn't need a battery. (I'll arrange for a proper source) I'm quite a DIY person, and I've got some...

What exactly do you mean by this? How can someone build a cheap 50mW aixiz laser while they sell them for 125$ (five times as much as on ebay)

So basically I have two questions: - Do line lenses only work for one wavelength? - Does it matter how far I mount the lens from the laser? Plz answer if you know any of the questions. Thanks

I want a 50mW green line laser, The cheapest way to get one seems to be to DIY one. Say I'd buy this 50mW green dot laser: 50mW 532nm 3.0-3.7V /Laser Diode Module/Green Laser - eBay (item 260541750065 end time Jul-20-10 20:29:51 PDT) What do I need to look out for with selecting a lens? - Do...

@jib77 That's not a line laser, and there are no line lenses to be found on the site either. Thanks though. @prototype I know it takes 4 times the power to have double the brightness, that doesn't change the fact a 50mW line laser will be brighter than a 30mW one. ;) But that's not the main...

I need a green line laser of about 50 mW, but I can't seem to find any. I have found a lot of red 5mW line lasers, and a 30mW green line laser though... Do such powerful green line lasers even exist? Or am I going to have to DIY one and attach a line lens myself. Are line lenses only good for...

If my question or calculations aren't clear, please ask. This is quite an important issue, it is safety... I'd like some advice please. Thanks

Interesting, What I need, is the most visible spot, not the beam. Is there a difference in the visibility of those for a camera?

In other words, is it OK to assume that the power of a laser will be spread over the line? Making it relatively safe, as long as you stay further away than the "minimum distance" I calculated above. Thanks

Hello everybody, I've been reading for a while on this forum, and have learnt alot. I've found one old existing thread on this topic, but I'd like to start a new one. I want to use a laser line (like the ones used on woodsaws), but alot brighter. Since the laser line will have a chance of...
