they will fit fine, your glasses probably will push up against the rubber on the goggles though. It might be a better fit if you take the rubber off, it all just pops off anyway.

If you keep the rubber on just push your glasses as far up your nose as they go ;)

You might also be able to use a dremel to make an indent in the rubber so your glasses don't push off of it .

That was josh's suggestion to me .

from houston originally- kingwood more specifically. it's pretty cool cuz hightechdealz is in the woodlands (like 30 mins away) too.

where are you from?

Re: GB 405nm Goggle $35 (Laser-Wave)

I just remembered an important question...

The 405nm laser diodes have significant sideband power at even shorter wavelengths; will the goggles deal with that as well?

(For reference, oogle the Sanyo datasheets, which IIRC show about 20nm of low-side modes.)

huh?!? now that would be news for me! cant really believe it, but then, theres stranger things.. ;-)
a few nm would be "acceptable" for me, but hell, 20nm?
the diodes are quite "broad" in the meaning that there are some up to 408nm central wavelength (which is much more visible than 405!).

about the googles: i'm sure they arent dichroic, but "simple" pigment-based absorbers. i am quite sure that they will absorb lower than 400nm well, with no significant transmittance below 400nm at all. remember, plain glass and plastics begin to absorb uv eventually!) and will have a (hopefully sharp) cutoff at, who knows, 420nm.

Re: GB 405nm Goggle $35 (Laser-Wave)

Okay, folks. Just to illustrate why you need good goggles...

Today I was feeling like shit for various reasons, but my tremors are doing better, so I decided to cheer myself up by massacring an Xbox HD-DVD, and was actually successful in harvesting the diode (due to fine motor damage, that's almost a first for me, so it's the first time I've tried with an expensive diode). After connecting it to my ESD protective socket, I stuck it in a stock AixiZ module with acrylic lens (a slightly ragged lens as I reused one that I had earlier attempted to "open up," but found my knife wasn't up to the job). A lab supply and 30 ohms worth of series resistance was used to power it. I tested it up to 90-100mA.

The picture attached shows a set of certified UV protective goggles, which are not explicitly certified for 405nm.

Note that I was behind the camera, one eye closed, the other eye shaded so it could only see the viewfinder.

With these goggles, I got corneal irritation, but no damage, from normal use, meaning no direct exposure to the beam and no direct reflections. The beam was observed with the spot (on a matte surface) hidden by my hand, briefly. The spot was checked at 20mA and 40mA against a matte surface, again briefly. Focusing was done with the goggles on.

I trust the point is well made.
