| My coworker has a 125mW green laser he uses to point out stars in the sky at night. It's an amazing little pointer but I asked him how much he paid for it and he said it costs 1800 dollars! That's a bit more than I've got to spend but I'd love to have a similar laser pointer. I found the following a sale on ebay for a 100mW green laser with a Buy-it-now price of US$20 and shipping+insurance of about US$40. So the total is about US$60 for a 100mW green laser. I am new to the whole laser thing and so I was just wondering what you all thought about it... do you think it's really almost as strong as my coworker's, and for about a 20th the cost? Or is there a catch? |

My 50 mw laser from ebay is ~30 mw green and ~180 mw IR... there is no IR filter in it...
It's a newwish laser pointer from ebay... I think the 100mw is almost the same... maybe 60 mw green and 350 mw IR ^^

| and to clarify, IR is infrared, invisible to the eye and thus is extra dangerous. it'll melt your retinas because you won't blink. it will also reflect off of somethings that are transparent in the visible range, so there might be no telling where that beam is going off of that glass window. |

Lets just say it easy: That laser has no IRfilter, then forget it! Whatever you do, dont buy it, you WILL get blind, or eyes will get damaged...

I have yet to find those things, as they would make nice IR filters.
Looking around with my IR camera, a lot of things are transparent to IR, but not to (parts of) visible light.
For example, I block my green laser with a piece of red acrylic, and the IR passes right through. This way I check my lasers for IR. |

| ebay lasers are known to be crappy, that's why they are so cheap! Because those lasers do not have an IR filter, the laser beam itself is not going to be as bright or as green. You'll end up paying 80 bucks and wish you didn't. then you'll spend a couple hundred more on another quality laser. Why don't you start off right, get a quality one off the bat and you'll save yourself 80 bucks! Ok, I don't know if anyone understood that... |

...I think I got that. But just remember. Almost always, you get what you pay for. If you see someone selling like... a 200mW laser for 40 bucks... somethings gotta be wrong. |

To be honest: that would suck. We're talking about lasers, we're even on a forum! So, just post the link. We are here to share information, not to be on our own utopia.
I should get a laser power meter, so I can really measure what is going on. |
