    Default Green laser line generator

    I paint the lines on parking lots and have been toying with cheap red laser pointers and line generators, now I am on the search for a green laser line generator. Parts would be fine (diode), any help or suggestions would be greatly appreciated. Thanks to all in advance, Ross.

    All you would need to do is affix a cylindrical lens to the front of an existing green laser - pointer or other style.

    Of course you still have problems when an insurmountable obstacle stands in the way.


    Another case of "it's not my job", I guess.

    Where would you suggest I find a cylindrical lens?

    I'm also interested. It would be neat if such a lens could be mounted on a cap that fit the leadlight.

    I found one a long time ago in some type of computer peripheral (a printer, more likely than not) that used a long bar filled with yellow-green LEDs. The lens was a long glass rod, which was easily broken into small segments. Those segments, when placed in front of a laser, caused it to generate a line.

    I'd imagine that you could acquire a glass laboratory stirring rod, smash it, and pick a piece that's approximately 0.25" to 0.35" long, and there, there's your cylindrical laser line generating lens. [img]/ubbthreads/images/graemlins/smile.gif[/img]

    Are there line generating diodes?

    Here is an optic...Merideth Instruments

    Here is a line generator I picked up to play with, basically a spinning mirror that will throw a line over 120 degrees wide, I mounted this to a board along with a green pointer for the line effect, works real good... Merideth Inst Parts

    I think the best choice for me is to buy a pointer and add a line generating optic. Will a higher power laser pointer (10-20,30mW) fry an Acrylic lens?

    No. It will barely warm a black garbage bag let alone a clear one.

    Leadlight is producing a green laser line generator. I have a sample - it works pretty well. I think the product will be available this summer sometime.

    Does Bigha work pretty closely with leadlight? I wish they'd make a rheostat dial butt cap to adjust brightness of their light. Bigha should too for their Jasper.

    I have a professor who complains about the brightness of a 3mW-5mW leadlight. The green is just too bright and dazzling for the class in a dimly lit classroom. A faint green dot has its place but can only be achieved with a dimmer of some sort.

    Sorry, I know this has nothing to do with line generators. But leadlight accessories would be really nice.

    PS. Nice to see you posting again.
