    You mean the X-axis label that would have shown -an optical density of <3 at around 488 nm, which is by coincidence the second strongest Ar emission line -a sharp drop to < OD1 starting at roughly 510 nm -no protection whatsoever at 532 nm -an OD of 3 or higher at 505 nm? I don't see how you...

    Except it's not 505 nm. I send you the raw data via mail and posted graphs here on the forum, those goggles are above OD3 at 505 nm. They dip below OD 3 between 507 and 515 nm, and the main 514 nm Argon wavelength is right in that gap (that's what started it in the first place, i messaged you...

    Point 1: Yes, please do that, every other manufacturer/seller of laser safety equipment does that Point 2: Do you mean this comment on some forum in a thread that no one who's owning those goggles is going to read? So what you're saying is that you knew for months that you sold faulty personal...

    Hi Gary, I just wanted to ask if you could give us a status update on a few things: 1) Do you have any new or updated OD vs wavelength charts for your goggles? You told Giannis in February that you would request updated graphs for your OD6+ 190-540 nm goggles, do you have them (or graphs for...

    Well, then find me a LPM with a sufficient dynamic range for the job... You can't burn the goggles, because that would invalidate the measurement and your LPM has to be sensitive enough to detect nW. You can't just use chinesium LPMs or cheapos that display "000 mW", because the goggles would...

    And again: A laser power meter is NOT at all useful for tests. There's no arguing about it, that thing is NOT used for optical density tests, simply because it is the wrong tool for the job. I asked a friend of mine who's working in the laser safety department of one of the largest PPE...

    Oh, they actually replied to an email. Their claim that they "did not get the picture of the 505 and 532 laser" is false, i have send them that pic as well as my data on the 24.2.2021 (see the pics below). Second: That EP 15-4 data looks weird, why would you measure the transmission if you are...

    So to sum up your answer: You do not plan to send EaglePair goggles to an independent 3rd party lab to get them tested. You do not have the equipment to properly test the goggles you are receiving. You are completely relying on the information the manufacturer sends you. You only perform...

    I apologize for what’s about to come, it’s not good forum etiquette, especially for a new member, but I have to say it. Sorry. I had to make a new acc for this forum, but I’m rather active on Styroypyros Discord, so members like Giannis or Cyparagon can confirm my story. It started in January...
