Seeking <5mW Lasers

Howdy Forum,

I'm seeking the opposite of what most of y'all want: I need low power lasers. Lasers that I have purchased from Ebay, although marked at less than 5mW, have been any sort of power. Some were as high as 75 mW. (We have a laser power meter.) That's no good for me or the teachers that I work with.

Of course, cat toy lasers tend to be lower powered, but they only come in red and use button cells. My teachers would much prefer AAA-powered lasers, and they'd like red, green, and violet. (Well, they'd also like blue and yellow, but we're realists.)

I'd like to pay less than $10 per laser. Do you have any ideas where I could purchase lasers less likely to char student eyeballs?

Thanks in advance,

Zeke

Violet lasers are usually 405nm ones. These are very close to UV, so they aren't very bright at all. If you got one under 5 mW it would be barely visible as a dot. I think you will find true 5 mW laser pointers are more expensive than the eBay ones you have gotten.

Like Paul mentioned, in most all cases, a guaranteed <5mW laser will cost much more.
An example would be this 5mW 532nm laser from Optotronics, it is certified to be 5mW, but it costs a hefty $29.95. :(

Edit: Here is a <5mW 593.5nm yellow laser pointer for you to dream about ....just slightly over your price point!

Thanks everyone for the help. It is a little bit of bummer that it is easier to get high power lasers than lower powered ones, but I guess that I'll have to adapt.

And someday I'll get that yellow laser.

I have this thing I bought while I was in China several years ago.

It takes 2 AAAs and is about 12cm long.
It claims 5mw but I have no way of measuring it. It is about the same brightness as those button cell dollar store pointers.
I don’t need it anymore because I’ve moved onto more powerful lasers.

If you want it, I can ship it to you from Vancouver BC (CAN). Should be about $5 shipping to the United States.
