405nm diodes can give you sunburn even at class IIIb levels

[creeg]

Heres a thought,you are sitting on the couch,messing around with your ClassIIIb laser and you point it at your skin and wham!!!you get a sunburn!So should we put and sun cream when we use our 405nm laser?

Why the hell would you be shining a laser at your skin?

The wavelength is too high to give you a sunburn. It will burn you though....

Your saying you've never shined a laser at your skin to feel the heat?

Of course I have... but after reading what it will do, and just to try it out once. I don't sit around shining a laser at my skin... do you?

Not to say I haven't singed my fingers on more than one occasion.

This is almost the same as another thread about the concerns of someone over the emissions of a 405nm laser his son had.
405nm is near UV wavelength but not quite there. You would burn yourself from the beam long before you could expose yourself enough to the near UV to get a "sunburn".
It just ain't gonna happen.

Now a 4 foot fluorescent blacklight can be very damaging but still not in the "sunburn" type way, unless you combine many of them like a tanning bed.

I didn't think a full face palm was warranted:shrug: I can switch it to a an actual face palm instead if you like?

 

[ShortyInCanada]

Nawwww. How about a nice "tropical" palm instead ?
Would go nice with the unseasonally hot weather here today.

@chipdouglas - See below:

Now that ^^^ is a face palm situation.

@creeg - Why the would you do that? Do you also stab yourself to check if anything happens? Just don't try looking into the laser while it's on.

HA ha ha haahh.
Don't let Creeg see that other thread about the shorting out of high energy power supplies.
He might try out some of those too !
