100mw laser question

[kostuhoss]

i just ordered green 526nm 100mW class 3B laser
( its my first laser ) it says that its with IR filter, does it means that iam safe without googles while iam watchind dot on white wall, burning staff etc?

 

[kostuhoss]

i payed 50 pounds (about 100 dolars) so it should be true about that IR filter

It could be without an IR filter or have a realy bad one for that price.Where did you buy it from? And with 100mW , no, you're not safe burning and looking at the dot on a white wall without goggles.And I think you mean 532nm.

Oh ouch! i hate to tell you this but you could've hardly made a worse choice.Ebay is a really bad place to buy pen lasers and spymodex is one of THE "most worsest" distributors out there.So if you get lucky enough to get a working laser, it will probably be less than 100mW and will not have an IR filter.
If you can cancel it, by all means DO IT! And buy from a real company.

You just bought a laser from a known scammer. I'd try to cancel that shit as fast as you can.

oh thanks, i will try to cancel it, anyway can you aeplain me about that IR what it is and if i dont have filter why i have to use googles?

IR is light just like green but it's at a wavelength beyond what you can see, and you need goggles because you can get hit with IR light and not even know until it was too late (eye damage)

 

[kostuhoss]

yhm thanks , damn i should ask before buing laser from ebay

You need goggles for green too not only IR: You need goggles for any color if it's higher than 5mW (basicly).

i hope they will answer my email about money refund and i take my money back heh

Also, I'm not sure what you mean by this but by all accounts, the price you pay is not a guarantee for quality or an IR filter. Especially not on eBay. And 100 dollars is simply not a lot of money for a 100mW laser, then again it's probably not even close to 100mW.

 

[kostuhoss]

oh good news, i received letter from the seller that he will do money refund with no problem , so now i have to find good company laser

 

[jamilm9]

if you want a pen sized laser nova lasers is the way to go

You are safe watching the dot on a wall, 100mW is absolutely nothing in that sense.

On the other hand, if you get hit by a reflection of the beam then say goodbye to your eyesight for a while.

[smiley=huh.gif].....SUNSPOTS!!

On a more serious note, besides sunspots, what does the IR actually do to one's eyes?(I know it's something we can't see but is harmful).
