Lately, I've been experimenting with a red LOC diode whose output I estimate at about 150 mW. I have no 650 nm glasses, and the power of the thing was pretty intimidating. So I came up with a solution that will benefit anyone with an iPhone and no access to safety glasses.
Basically, I built a cardboard enclosure that holds the phone a comfortable distance from my eyes, and attached it to a pair of safety goggles. Now the only thing I'm risking from a direct laser hit is my phone's camera. With the iPhone's accelerometer and magnetometer, it also serves as a cool VR-type HUD for games
.
You can use this rig for protection against any color laser -- you'll even be able to see IR through it, since the iPhone's CCD is sensitive to very long wavelengths.
Careful, though: it's a little disorienting, since there's a bit of lag between reality and the phone's screen. Also, you'll have no peripheral vision.
Always exercise common sense, and don't look into the beam or anything..this isn't infallible. The goggles could fall off or break. And remember that a direct laser strike will most likely do to your camera's sensor what it would do to your retina - that is, burn holes in it.
