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.
