The Phillips Safety team is proud to provide a great assortment of high-quality laser window films to our customers. As laser protective removable window films, they can be used in laboratories, production facilities, and operating rooms to protect workers from the glare of lasers.
NB Product Page
When choosing a laser window film, it is important to look at its Optical Density (OD). At Phillips Safety this information is available both in the description of each product as well as in the wavelength information tab of the product’s page. There you can visualize the full information on the optical density and wavelength of the filter.
As a guarantee of their quality, Phillips Safety’s laser window films meet and/or exceed ANSI Z136.1 and CE EN207 safety standards. They are available in light blue and orange colors, with 30% of visible light transmission.
Our laser protective removable window films are available in three different laser filters: Argon and KTP; UV,Nd:YAG and Diode; andUV,Nd:YAD and Holmium. In addition, they can be manufactured in custom dimensions.
Hi.
If the need for viewing the lasering process is solely monitoring, the most affordable and 100% safe to ones eyes is a camera, connected to a monitor, PC, tablet, etc.
Used ones can be had for free if You happen to be in the right place at the right time, new ones aren’t that expensive either.
Unless You’re talking smaller than A6 “postcard” size, the price sounds IMO/IME too good to be true to be actual laser protective material.
That stuff is crazy expensive as @misken there pointed out.
That’s the ballpark price range I also came up with when hunting for a viewing screen for my DIY enclosure.
So camera it is for me.
I use those for lighting purposes every once and a while, and I seriously doubt that those would work as intended.
Interesting idea though, I have to test it at some point.
You can test it as well, keeping mind that when burned/evaporated, the gasses and fumes released will probably cause both health issues for You and corroding problems for Your machine unless the ventilation is adequate.
Just do a low power material test onto paper/wood/etc. with and without a gel on top of the material.
Then You can determine how much of the power is absorbed by the gel and how much goes through.
But do use adequate ventilation and make sure that You don’t inhale the fumes if You decide to test any plastic material.

If your co2 is ir, then how could it possibly cut them?..
They supposedly are made from polycarbonate, polyester plastics.
IR is a very wide range of frequencies… my ir fiber would probably go right through them.
Where did you get the photos? neat…
Lasers are not very useful without a lens. Once it passes through the lens there is a focal point, past the focal point the power drops off very quickly. Put something that reflects the beam and the power drops so much it’s pretty much useless. A couple inches away from the focal point on my 40W co2, I can’t mark a Kleenex tissue… virtually no power… wouldn’t stick my head in there and look at it either.
If you want to learn more, please visit our website Laser Protection Film.
I’m sure all of us have used a magnifying glass to burn wood or other objects. This is how most lasers work… the beam is focused down to a small point where the power density is much higher… once it’s out of focus there is no power to do any real work.
The sun produces a very wide range of emf, including x-rays and gama rays from the suns corona. This damages the dna in your cells.
Burn is generating a broad spectrum of frequencies aside from the actual laser frequency… When the co2 burns it produces lots of these frequencies of light that can damage your eyes and your protective lenses allow through… using a co2, the IR is not visible to human eyes, but it’s a very bright burn when it operates.
If you don’t know the frequencies of the generated light (emf) how do you know if the safety glasses are really protecting you from other sources of laser generated emf that we know damages your eyes?
After one or two jobs, my brain told me to not look at the cut point, it’s too bright so there must be some type of damage occurring… the fiber is mesmerizing when it runs, so it’s hard not to look … but required now and then.
If you hunt around you can find experienced, highly technical people that have the equipment and knowledge to test these optics. I haven’t heard any of them say anything other than the $250 high end laser safety glasses are no better than the $20 Chinese safety glasses. Who are you going to believe, the salesman or the technical people?
I don’t value testing these glasses enough to figure out how to test them without deep pockets. I would think just diverting the beam and using one of the many optical sensors we have could allow at least a proportional value. It would be non destructive to the glasses and give you a good idea of their effectiveness at that particular frequency…
Sorry I was long winded, but I get tired of decisions generated out fear and not from facts.
All I’m saying is listen to everyone, we all have opinions, good or bad based on something. If the base of the opinion is from an Illumination Engineer, that might be more useful than the guy who’s doesn’t know what a laser is.
Use your knowledge along with your research and your common sense to guide you.
Understand how this stuff works is probably the most important lesson you can learn. Then you can separate the from Shinola. You will be safe, comfortable and happy with your decision… as it will be the best decision you could possibly make.
Then you can add your opinion here
Safety should be on every ones mind at all times when operating any tool/machine …
Good luck…
