IMPORTANT: Laser safety glasses SHOULD be tested with a laser power sensor to be deemed 100% SAFE. I have not done this with these glasses. Use at your own risk. Test with a power sensor to be 100% confident in any pair of laser safety glasses you own.
Good to see thing being referenced at the discord. As you also noted, to be absolutely safe and sure about the laser's transmission this should be tested with a laser power sensor. But the again, there will most likely never be a 100% beam transmission towards your eye and due to the diverging beam the power will be much much lower, We should still always wear the correct laser safety glasses when handling any type of laser. I think it is still not a good idea to keep staring at the object being lased as you would also not keep staring at the sun. The high intensity visible light is also not good for your eyes
Thanks, just in time as I was looking for a pair and did not want to pay $200+. I'll follow the link in hopes you get some credit from the seller for a new pair. Good videos you put out, thanks for you hard work, it is appreciated.
Thanks Mark! Glad you got value out of the video! I really do stand by these lenses and trust my vision with them every day. I hope they serve you well - we'll see you in the next video!
Finally a FULL PROOF review! I knew you would have something! So this will pass for xTool D1 20w- blue & 2w- red laser then? Well, I ordered from the link!
These glasses are for 1064nm wavelength (fiber laser) but FreeMascot does make them for diode wavelength though (455nm) you can find them on our website at www.lasereverything.net/buyingguide/
So my understanding is that whilst the 1064nm is dangerous to the eye, it's reasonably unlikely you could get a reflection to hit you. However, what is dangerous about "watching the thing lase" is similar to welding where you are getting the thing itself flash off all kinds of invisible high frequency stuff, and that's the most likely thing to stuff up your eyes? This is a question rather than a statement? I don't know what kind of ranges that sort of thing would be creating, nor what kind of protection you would need? (Obviously don't look at the white beam is the main thing - I try and use my phone camera to do this and peak at the camera screen from somewhere out of view of the laser)
Bottom line is you should always wear safety glasses. Laser beams still fan out despite their focused nature and even if you aren't catching a direct reflection, reflected 1064nm lightwaves are bouncing off your item and scattering all over the room, flooding it with invisible radiation. It's not good for your eyes or your skin and you should always wear protection. Just because you aren't instantly burning your eyes with a directly reflected beam, doesn't mean you aren't slowly damaging your vision over time. Also yes, absolutely the brightness is terrible for your eyes just like when you're welding. Looking through your phone will block a direct reflection and the brightness but doesn't protect you from the ambient radiation in the room. If I were you I'd just wear the safety glasses. Better to be safe than sorry as with most things.
brilliant and informative. Question. do the glasses have to be for a certain specific wavelength or can i get the glasses with the highest protection and use it for all the wavelengths?
You want to buy them for the specific wavelength. Some safety glasses are made for a range of wavelengths, just make sure your wavelength is included in the range.
you need to use a power meter to test your glasses , if you don't have any power on the sensor it will be ok , less than 1w of power on the eyes is dangerous
I'm way behind on catching up on all your material... but putting in the effort. I was wondering... have you ever tested out some eye protection that didn't protect as it said?
I wish they had some kind of data sheet to look at. I know capturing that data is why the Phillips cost so much, but you would think somebody somewhere would've tested them just out of curiosity.
That would be great, although that can be some pretty pricey stuff. The optical power meter sensors I'm familiar with read really small numbers (in the micro Watts range). I would be really interested to see what your test setup is when you get it figured out. We do a lot of work with Thor Labs equipment for LIDAR packs and such.
@@timt1346 Absolutely. We're looking at the coherent kits right now. They're expensive but seem accurate and effective and I really want a name I can trust for this purpose.
Thank You for the recommendation for these safety glasses, very informative. I am looking to make an enclosure for my fiber laser as well as my Ortur Master pro 2. Can you recommend a safety glass/acrylic for a window in these enclosures. Any insight would be appreciated. Thank You, Keep up the great work!
While expensive LaserShield Windows by NoIR offer the best protection and are currently my recommendation. Check out the YGW material for Fiber and the KRW material for Diode: noirlaser.com/lasershield-windows/ Sold by the sq ft.
I'm super suspicious of the safety glasses that came with my Fiber Laser! They were a no name brand and the packaging said nothing about 1064nm (or any nm scale) or anything about fiber lasers at all, and the safety glasses just seem like just dark sunglasses style lenses... They definitely are not yellow lenses like every other 1064nm safety glasses I've seen.
Gotta watch out for the cheap crappy throw in glasses. I've heard a lot of spooky stories. It's not much more to get a slightly less sketchy pair of glasses that do a much better job for sure.
The red you see is only the alignment led, basically what you would use to play with your cat, and isn't powerful enough at ~5mw to be what is marking the lens in this test or the solid aluminum plate at 2:45. The red light pointer operates at a wavelength of 655nm, so isn't really what these glasses we are testing are meant or targeted for. Fiber is in the non-visible light spectrum at ~1064nm wavelength, so you can't actually see the beam that is getting absorbed and marking the lens. Because of this, you can actually go blind operating this engraver, and not even see if running. This was done with a 30w Fiber laser. When you see us test the laser ~2:45, the light being emitted on the surface that is more blue/white is actually the reaction of the aluminum plate being ablated by the invisible IR fiber laser. Hope that explains our thought process for this test, and sorry we didn't meet your expectations. We're always looking to improve, and appreciate feedback.
Good, however, I still have no idea where I can get safety googles I can trust. I have a brand new 60W JPT MOPA fiber laser sitting idle, not tested since it arrived a few weeks ago, because I cannot get protection eyewear I can trust. I have purchased several, one pair directly from Cloudray, another from Amazon. They all come unbranded! Neither on the husk, nor on the goggles can I find any company name. I have no idea if they will work with 20W/30W/50W/60W/100W fiber lasers, if they are meant for 3W lasers only, if they are meant for 10 minute per day or 6 hours use per day. Are they tested before shipment? No “OK” check mark is found, no production year/month/date, no serial number, no printed material whatsoever, not to mention a certificate. What if there was a glitch in the production, what if the coating applied is too thin, are my own eyes supposed to do the quality control for the manufacturer? Safety equipment MUST be traceable back to the manufacturer! And it must be checked before packaging! My brand new very expensive laser is still sitting there, collecting dust. Ingvar Nilsen, Norway
Depends on the wavelength. I'd probably recommend getting different glasses for those as they are much shorter wavelength, 355nm UV and 5xx Green where as fiber is almost twice that at 1064nm.
@@LaserEverything thanks very much for your answer. I have a green Laser pointer that states it is 532 nanometers (plus/minus 10 nanometers) . Would you glasses work? Thanks again
They are tinted, so it may offer some eye comfort from brightness. If you're looking for UV protection from the sun too, I guess you'd probably want to validate that wavelength coverage for that spectrum of light. Most generic sunglasses I doubt are rated in the same way and just tinted, but guess it just depends what it is exactly you're looking for.

This has convinced me to buy them thanks for the detailed video.
Been trying to understand half of the day what I needed; considering buying XTool IR to swap back and forth with my D1. Thank You!
Safety First!

You want to buy them for the specific wavelength. Some safety glasses are made for a range of wavelengths, just make sure your wavelength is included in the range.
you need to use a power meter to test your glasses , if you don't have any power on the sensor it will be ok ,

I'll look into setting up this experiment
Do you have a power meter you would recommend?

Thanks, ordered mine today.
Nice :)
I wish they had some kind of data sheet to look at. I know capturing that data is why the Phillips cost so much, but you would think somebody somewhere would've tested them just out of curiosity.
Hopefully that will be us soon. I'm looking into purchasing the required hardware to get some legitimate testing done.
That would be great, although that can be some pretty pricey stuff. The optical power meter sensors I'm familiar with read really small numbers (in the micro Watts range).

Would have liked you trying it with like a 5 watt laser AND not just red. That is what I would consider a very unscientific test.
The red you see is only the alignment led, basically what you would use to play with your cat, and isn't powerful enough at ~5mw to be what is marking the lens in this test or the solid aluminum plate at 2:45. The red light pointer operates at a wavelength of 655nm, so isn't really what these glasses we are testing are meant or targeted for.

I'm not sure if they ship to Norway but since this video we've begun recommending NOIR, I'd look at goggles from them.
Does they work for green and violet laser? Thanks
Depends on the wavelength. I'd probably recommend getting different glasses for those as they are much shorter wavelength, 355nm UV and 5xx Green where as fiber is almost twice that at 1064nm.
@@LaserEverything thanks very much for your answer. I have a green Laser pointer that states it is 532 nanometers (plus/minus 10 nanometers) . Would you glasses work? Thanks again
No, this safety glasses can not work for green laser.
what about the wickedlaser's laser cube you find at club with multicolor or nm wavelength?
Do you know if I can use this like sunglasses?
They are tinted, so it may offer some eye comfort from brightness. If you're looking for UV protection from the sun too, I guess you'd probably want to validate that wavelength coverage for that spectrum of light. Most generic sunglasses I doubt are rated in the same way and just tinted, but guess it just depends what it is exactly you're looking for.
@@LaserEverything thanks 👍
Please tell us, any of lazer safety glasses block Infra red scaner rays? Did you try it? Thank you
