Anyone know if these glasses work for a violet laser?

I would not use those. Those ENHANCE laser visibility. You want to decrease visibility. The ones that I bought work very well and are very comfortable (link in earlier post).

Remember, you get what you pay for.

I believe you actually have the same laser as me. How did you find the wavelength for your module?

If you have a blue or violet laser, it will be in the 400-450ish nm wavelength.

https://en.m.wikipedia.org/wiki/Blue_laser

The glasses I linked to, which are the same ones as Admin's glasses will block 190-550nm
These are also OD6 which will reduce the intensity by a factor of 1,000,000

Compared to the cheap ones I got with the engraver, I cannot see the beam with these.

Any idea if there's a Canadian source for those? Shipping across the border is murder.

Edit: Saw an earlier post jokingly mention using a welding mask... Would that actually work? Welding googles may actually be more accessible for me.

I have a welding mask but being that it is not made for laser, I don't trust it. The website I linked to earlier has an international site. I will try to find it. I believe the shipping rate is a flat $32usd.

I will edit this post with the link when I get to my computer.

Worst case, do what I did when I had the cheap Chinese glasses. I took a cardboard box, cut a hole in it and mounted a computer fan. Put that over your engraver and look through the fan to monitor. Still use glasses.

Or better yet, add a webcam in the box to monitor on your computer.
