I bet if you made one for Harry & Megan (for pest control), QE2 would give you an OBE.

You are a flashaholic if you are forced to come out of the closet, to make room for more flashlights.

Oh wow, awesome mod.
Never seen a blue laser before.

This is where passing college physics and biology can be of practical use: understanding how the higher energy of blue light photons transfers energy to electrons, specifically. And what a free radical is.

Quote:
The blue wavelength can cause a distinct biochemical action in the release of free radicals which are then effectively absorbed by red blood cells in the capillaries. Blue laser light, 445nm or 470nm is absorbed more effectively by retinal tissue ….

It’s a nice looking unit but I see none of the expected placards for a class IV laser. Does it have the required safety lockouts? It is unlikely this device could be legally imported into the US without them. Other countries, I don’t know. At 400-500 nanometers permanent eye damage happens almost instantly from a direct hit, or even from specular highlights. This is a seductively beautiful but exceedingly dangerous device to be messing with, as are all lasers above one watt. Blue is the worst.

I think that the legal power is 5mW max.They are imported with fake specs,or as simple flashlights.
I have 3 blue lasers.One 500mW,one 1500mW,and one 5000mW,together with a “Sanwulasers” 3X beam expander,which reduces beam divergence by three times and extends the visibility range of the laser beam,and of course a pair of special protecting glasses.
Of course they are very dangerous,and not only direct hit produces blindness,but even reflection on a not shiny surface could harm the eyes.
And of course don’t get close to airports turning on a laser.

400-500nm is the wavelength of light, aka the colour. Generally anything above 5mw isn’t legal for importing but Glasses

Anything above 10ish mW is regarded as dangerous. Power is where the danger is unless you’re referring to the odd effects of blue light specifically.

400nm is purple
445nm is blue
~488-495 is a beautiful shade of teal
500nm is green

Now thats a real beauty. You must have put so much time and work into that. Really love it man. But I do have a complaint! Where is the arbitrary picture of it burning through something in focus at close distance?! Big Smile

It looks beautiful like everything you make! Why such an odd battery though?

Sorry not to be clear. There are many factors at work to cause cell damage, a few have been mentioned. The easiest to grasp are power, wavelength, and contact time. A 0.5mw helium neon beam, focused tightly enough will cause damage. The normal charts really don’t factor that in. That’s okay. Diode lasers are pretty sloppy and it would take a sophisticated (expensive) optic to get one tightly collimated enough to do damage at 0.5mw. The way I read the specs above, it is a 1.6w beam. The safety glasses pictured are not something I would wear, as they could allow spurious emissions in. At that power it wouldn’t take much. Perfectly tight fitting goggles are my choice.

Lasers are big fun. I traveled around doing laser light shows for a living back in the eighties. Just CYA before turning one on. I wonder how the CDRH is going to regulate hand held LEP emissions. It will be interesting.
