I used to us mine to check for body fluids when I stayed at a hotel. It also works for killing microbes in your toothbrush.

What do you do with your $9 ebay 405nm laser?

Does it really work for that? I thought :thinking: about trying that but I don't stay at hotels very often.

Yes it does. Shows all kinds of organic stains. You can see the spots they missed in the bathroom too.
Nothing worst than seeing a glowing spoog stain on your pillow. :barf:
You have to defocus it though.

How dangerous are these purple lasers to stare at the reflections.
Many of you are saying these are overspec (30-70mW?). I'm assuming that includes the UV that is invisible to us, so we might be seeing 15mW of an actual 30mW for example?
Can this UV reflect back and damage our vision?

The UV spectrum is quite a bit lower than these lasers produce, the reason you dont seem them too well is your eyes are not sensitive to the 405nm light. Its something like 5% sensitivity where a green laser is around 90% sensitivity. It is harmful to your eyes to catch a direct reflection but off of like a white wall shouldnt be too terribly bad.

You can get damage from an IR laser. Regardless if you can see it or not, a laser beam will do damage to your eye. Its the power of the beam and not the color.
You should always be conscious of where the beam is reflecting. Even from 10mW laser. When you get into 50mW and above, then goggles should be involved.

No, direct injection lasers emit one wavelength. That one wavelength is around 405nm. Also, we can see UV, but it's obviously dimmer. Look up "eye reponse" under google images.
They are useful for making pretty pictures....:yh:

I remove the diode and make a 445nm laserpen of it.
Well, when i first got it (i don't have the equipment to test this) my laser was around 30-50 mW... (going off what people have said to expect from a 405nm) so, trying to figure out if i could make it stronger...
well i pot modded the thing, it's only 9$ so why not? i never could get it as low as some i've seen or heard of... but i did make it intensely brighter...
and when i put in the lens from my 5mW green ebay laser i was able to burn some things... not very well; but it did work.

I bought a glow in the dark sheet, and sat it in a corner, while I write "Buy Me" on it when people pass it in the Mall. I've sold the $9 pointers for up to $60 a pop when people see this... Tell them it's new technology yanked from a blu ray player, and they're hooked(usually, older people seem to be afraid of it).
Anyways, there's a way to make a few extra bucks(-=
