    Default What are you all doing for laser cutting glasses?

    Hello!

    We have a new fiber disc laser, runs around 1030nm and 6KW. Our machine's windows are proper filtering windows but with a rather high VLT, but it's still a rather bright process and operators are complaining about the headaches and vision spots.

    I know a little about OD protection, I used to play with DVD, bluray and other high powered lasers. What I'm unsure of is how much help adding a second set of high VLT glasses with ~+6OD protection around our working wavelength would actually be.

    I found these glasses in a quick google search, I'm sure they'd be great for working up close and personal with the laser module but I'm unsure how much of the eye strain comes from the laser light and how much comes from the light of vaporizing metals. It seems I would want to look for a set of glasses with lower VLT and extra protection around 600nm or so. These are 10% VLT and it seems they pretty much only pass around 600nm!

    I do know throwing on a set of welding shades actually makes the situation worse for visible wavelength lasers as they force your eyes to dilatate and the shields themselves are lacking on OD around the common visible laser wavelengths, I don't want to order an expensive set of shades and find that's happened...


    What are you all doing for protection while configuring cutting parameters initially, watching for popped parts, and other common laser cutting operations?

    Thanks in advance for any and all advise!

    A can of spam has a couple of nice tabs to affix the string to keep it
    on your head, in front of your eyes.

    No nasty laser beams getting thru.....

    However, this thread should "Bounce Google hits" nicely eh ?
