    OMTECH 100 watt ghost lines??

    The 100 watt (red/black style) Chinese OmTech laser was working fine until ghost lines started to appear while cutting and sometimes during engraving. I checked mirror alignment and all 3 are centered properly. They are all clean as is the laser tube output. Today I installed a new focus lens (1.5") and although the lines are a bit sharper I'm still getting ghost lines. Please see picture.
    Can anyone advise me as to what may be causing these phantom lines? Thank you!

    What type mirrors are you using? I had ghost lines like that on my new 90W tube just before I burnt a hole in and cracked the first mirror. I had gold over glass and converted to gold over SI. Problem solved for me.

    I don't know what mirror type but I ordered 3 new ones from Amazon that I hope get here tomorrow. They "appear" clean and clear of scratches. I'm just surprised the new focal lens didn't help. Thanks for your reply!
