When it comes to safety gear, the prices get inflated a huge amount. This applies to racing equipment, a $10 fire extinguisher becomes $100 when it goes into a racecar even though they are essentially identical. There are some differences, that might one $15, but not $100. So the question is always what item is better and what is just over inflated price? btw, how about one just wear an eye patch on one eye, so in the worst case, you still retain vision no matter what.

Sorry late to the party and hope you found a solution. Yes an interlocking enclosure that physically disconnects the power source from the laser when the door is unlocked is the best option, and the same applies if using a glass/plastic window, assuming the material is rated for the laser wavelength and power. For a class 4 laser, goggles are for when using an enclosure isnt feasible for your work, like when working on a laser table. I would never use any of those glasses in the video for class 4. Goggles rated for the power and wavelength of your laser, fit your face and block out all external light with a gasket/foam, thats what i would use if not using an enclosure. For extra safety i would wear the goggles when interlocking and opening the door, take off after.

I run an optical lab that basically makes prescription eyeglasses for safety and for everyday eyewear. I think this is something that is going to be needed to be addressed by optical labs to provide. From just a quick search on this, it appears that the laser safety glasses that are linked are tinted to a specific color in a polycarbonate material, most likely at 3.0mm thickness. I have my own Ortur unit coming in about 2 weeks myself. I can make my own prescription lenses in a safety frame and get the correct color tint. I'm not sure yet how that measures up until I can do some more research into this. About a year ago a student from the University of Chicago approached me about doing this but I it fell to the backburner. If you can reach out to me with more information, maybe we can come up with a real solution for those that need prescription and trying to fit these over their eyeglasses isn't working.

Is it possible to find a sheet of the polycarbonate to make a top for the enclosure so that people who walk into the shop are protected without the glasses?

Search for plastic fabricators near you. They have the capability to cut and heat form plastic. The dust collection system could probably cope with smoke from cutting wood but would offer no protection IMHO from the toxic fumes from cutting plastic. The enclosure for your laser is important as any optics are sensitive to dust.

I am looking at getting an engraving laser. One of my main concerns is of course safety. Knowing what safety glasses is big concern. I asked someone at an optometrist office if they had any recommendations on selecting the correct safety glasses. They could not recommend anything specific, HOWEVER, he suggested doing a test of sorts. Place a piece of fruit such as watermelon on the target surface and place the glasses between the output laser and the target object. Then, while not looking at the engraver, flash the laser. If the target is burned or damaged, the glasses are not sufficient. It would be great if one of you experts could come up with a test of this kind. Thanks.

I am left shaking my head at this! I am sorry but this is a stupid and dangerous concept they recommended to you. Laser light is coherent light and can travel over great distances as a nearly parallel or collimated beam. What this means is that the effects can be accumulative much like standing in the sun for 10 min will not lead to a sun burn however 2 hours will. Think of the glasses much like the differing SPF ratings for sun screen. So this again is a silly concept. Second your retina is NOT a piece of fruit and can be damaged far easer. I would also suggest reading this for more information: diy3dtech.com/guide-to-laser-safety-glasses/

I think what's missing is a chart or data sheet that shows you the OD level as it applies to the laser wavelength. For example, if you see some lenses where it has an OD4+ at say 560nm-880nm then skips to like OD6+ at 1100nm-1350nm, then OD4+ at 2230nm-4800nm. This raises two questions: 1. What happened to the range between 881 and 1099nm? 2. Why did the OD rating go up and then come back down at the different frequencies? If you can look at the spectral chart, you'll see the dips and spikes in the frequencies where the lenses will absorb the light energy and where it won't. The biggest problem with laser safety lenses is that it's not a one size fits all. You may need 3 different pairs of glasses to filter each frequency range for a diode, fiber, and CO² laser you might have in your shop. Anyway, not trying to steal the show, but these are difficult topics to answer for even the best of us. I had to have a PhD explain it to me at work so it worries me for the world at large who doesn't have access to this kind of information.

When I wanted to used it again I was still on the fence about the color so I looked again and saw this video.

I think your missing the point as these are order of magnitudes (i.e. the 6) so this is a LOT. Keep in mind the purpose of the glasses is to defuse the condensed reflected light (this is easier in the IR range then visible). Also note for the CO2 (which I have several) is when the light hits acrylic its turn heat rapidly because of its longer wave.
@generalawareness101

@@DIY3DTECHcom No, not really missing the point because they are to keep the beam from destroying your eye while also lessening how bright it is (like looking at the sun). The Optical Density numbers range from 1+ to 10+ and in spectroscopy, optical density is the measure of absorbance, and is defined as the ratio of the intensity of light falling upon a material and the intensity transmitted. The greater the OD the less light hits the eyeball (hence it being darker). 6+ is not enough for me with my CO2 and barely enough with the blue laser.
