    Focusing on mirrors

    Hmm, doing something wrong here. I've got my M140 w/ G-2 lens pointed down the hallway (50+ ft) and focused as much as possible...dot the size of a fingernail. Collimated? When I grab a second G-2 lens and place it in the beams path (a foot away from the collimated diode) I get this spilled...

    Focusing on mirrors

    I'm 100% certain your clarity is spot on and my knowledge is lacking. :) No, this makes a ton of sense and I greatly appreciate it. Final question is in regards to the actual application: I'm using a G-2 glass lens directly attached to the diode and (fingers crossed) can use a second G-2 lens...

    Focusing on mirrors

    Hi, diachi! Thanks for this. Excuse my ignorance but I'm not exactly sure I understand the process/properties of collimating the beam. Am I basically focusing the beam twice? Once when it leaves my diode, and again when I know the remaining distance to the object to be cut?

    Focusing on mirrors

    Agreed! :thanks: I wear my safety glasses even when I know my variable PSU is at 0 amps / 0 volts. I have this insane fear I forgot to turn the knobs last time I used it. Probably a good habit. Stay tuned for updates!

    Focusing on mirrors

    Love that spirit! I definitely will! I'm going to set up a pretty simple layout like my diagram above tomorrow (pending some mirrors from eBay) and let you guys know how it goes. What's the worst that could happen... :lasergun:

    Focusing on mirrors

    I wish I had paid better attention in science class. I'm assuming my 40W laser can accomplish variable distance without noticeable loss in focus due to brute strength...? I wonder if the M140 can accomplish variable mirror distances even on a fractional level...say between 6-12in without...

    Focusing on mirrors

    Hi, all! I've been reading the forum for some time now. Finally decided to register and ask a question! Thanks in advance for the help. I have a few M140s that I'm experimenting with. I've attached one directly to the moving head on my CNC machine and it's been neat. I also have a cheap...
