Re. the IR being emitted in a conical beam-shape:
When I tested my Newwish laser, observing the dot at 17-feet with an IR (nightshot) camera, I found the IR dot size to be about 2 to 3 inches, while the green dot at that range was about 1/2 inch. So the IR was certainly not well-collimated, but it was 'tight' enough that accurate LaserCheck readings were impossible at any range.

UPDATE!
If you read a few posts back you will see pseudo including an email conversation I am having with this guy, that works for spymodex.com, and sells on ebay under shane.dominic. Here is the latest in that..
This is the email I sent him after he replied (the response pseudo posted)
"The only reason it took 4 months is because of shipping problems... And I assure you, the laser does not have an IR filter. I asked you if the laser you will be sending me has an IR filter and you said it would. That is false advertising and very un-safe. You say a laser is unsafe regardless... I already know that. The thing is if I have safety glasses designed to block out 532nm, and use them thinking I am safe, I would be a fool. The laser you sent me is putting out so much IR that even with safety glasses, the IR would blind me!
I can provide you with a link to a forum posting about this laser I got and you can see the stir it has created. All I ask for is my money back, and I will leave it at that.
the link is... http://lasercommunity.com/viewtopic.php?t=8140"
This is his response to my above email
"Hi.
I will be as brief as I can. If you look at http://www.greenlasers.co.uk/first.html which is a link from the person saying that lasers with an IR filter produce much less power. This link states clearly that if the filter is missing, thete will not be much power change. Also, to say that a true 60mW laser is really something like a 1 watt laser is crazy. It would take something approaching a car battery to power it. There is nothing at all wrong with the laser sold to you and as I said, due to the timescale, I cannot offer you a refund.
Regards"
Okay.. so after reading that email from him... I can safely say he is a moron. His response is really.. stupid. So this is my reply to him that I just sent a few minutes ago.
"Okay... I don't think you are getting this. The laser you sold me is garbage because it outputs BOTH IR and 532nm light, making it appear brighter and more powerful then it is. I don't want an IR & 532nm laser... I want a 532nm laser. You are either not very smart or trying to confuse me by saying things that don't matter to the situation.
I want a refund on this laser, and If you wont give me my money back I will file a claim and deal with paypal and ebay about this. Do you really want to have all of this done against you, or rather respect the customer and give me a refund.
Brandon"
So I dont think this guy will be very nice about a refund...

I agree, sounds like the guy is an obstinate moron. Either doesn't understand, or doesn't care.
Good luck with the refund but at this stage I would not be too hopeful.

1 Watt laser requiring a car battery to power it? Interesting. It sure makes me feel special to have an RPL with a 2.5W diode that runs off of a single 3.7V 2300mAh 18650 battery. I'd definitely make some good money if I could replace car batteries with those  . Maybe its time to send him an e-mail myself... not that he'd probably listen to me either. Anthro, can you IM me his e-mail and some general details? Thanks.

Seller dig_that_groove sells legit WLs. Other than that though, its very hit and miss on ebay, with the majority being "miss".

You know ebay can be a great way to do business generaly for a lot of things... but it strikes me that for some reason there are a few products that are more prone to being rip offs.... LASERs seeming to be the biggest one of all.
Other then DTG in the pointer market they ALL seem to be scammers. I have a feeling when you're dealing it table-top and non pointer models that this effect lessons probably because its less of a thing the avarage joe would get and the shadey people just dont know what they are doing in that reguard...
Crasy times man, crazy

| Well, not all scammers, but all these hyped up green ones for sure. There are some legit CNIs on there and I have sold CNIs to people who ended up listing them on eBay. I've also seen some good lasers like the Herc and PGL/Aries on there, and if you make sure you understand what you're getting, the gas lasers like HeNe and Argons aren't bad. Now that I think about it, yeah, pretty much just those hyped up greenies as things like diodes and other supplies don't seem to be too bad either.

Here's some views of the IR spread from my 'eBayser'.
In the second picture, I have blocked the beam with a dead match in an attempt to prevent my camera overloading so that I can examine the corona.
The IR appears as a ring around the dot and a fan-shaped pattern further out. This pattern is repeated on the other side of the dot too about 180deg away. It isn't visible in the second picture because it is out of the frame.

| 808nm pattern appears fairly weak and diffused. 1064nm may still be a bit high so be careful of that even when using safety glasses designed for 532nm (green) as they will likely not block much of the 1064nm unless it is stated to do so i.e.- (OD 5 @ 532nm / OD 6 @ 1064nm), that would be safe ratings. |
I posted some other comparison pictures somewhere. My Fusion and goggles arrived today and it is rather reluctant to output anything over 100mW, no matter what batteries I give it (excepting lithiums, which I've not tried yet).
The difference between a well-made laser and a crappy eBayser is remarkable. I photographed both lasers through the goggles in IR sensitive mode on my camera.
People.... Please... Realise that you are not getting what you pay for and you are seriously risking the safety of your eyes, even with goggles... IR will pass straight through these 532 goggles from WL... and they are good goggles... They're not crap !!! It's the eBaysers which are crap !!!
I would rather have a moody fusion than a "high-powered" eBayser.
I'm getting my money's worth in quality green light !!!!!!!
Don't buy crappy eBaysers.
Don't rely on the seller knowing what an IR filter is or why it is necessary.
If you asked them if they come with reverse dialectric multipolar clitoral stimulators they'd probably tell you 'Yes' just to get another sale...
(Not all eBay sellers, I have to admit... I have had one seller tell me that his lasers probably won't be suitable for holography, even though he is claiming that they are high-spec lab-lasers with IR filters, etc... etc... He'd rather lose a sale than have a dissatisfied customer. That sort of person is a good eBayer. What a shame we can't leave feedback for someone we haven't made a trade with).

pseudonomen137 thanks for the videos and informing us about the IR emitting lasers.
RoadRunner and pseudomen137 I bought an Ebay laser and before I pay they answered all my insisting questions that if it has IR filter that it has.
I am still suspicious if it has.
Can you recommend me any methods that I can check if it has an IR filter or not. I have a webcam that I can see IR light but haven't got any goggles that can filter green light.
I is a 30mW laser. I bought it just for the beam. All I want is to see the beam at dim light in daylight conditions indoors as at night. I don't need to burn things.
As I discovered that the beam of 5mW cannot be seen even at night I decided to buy the laser of which beam can be seen, having the least power output. I bought a 30mW one. And it gives what I wanted. Also I prefer WL or WickedLasers or DL lasers, they are more expensive than the one I bought. Of course they have better quality, better divergence, better collimination and better power output. These don't interests me if my ebay laser has an IR filter.
Please tell me any methods to find out if it has an IR filter or not. If I discover that it hasn't I will return it.
Vic suggested me to shine it on something that the green light doesn't reflect off, and that there's a possibility that the IR light will reflect off. Can this be a glass? I remember that green light will pass through but IR will reflect from glass.
Is this apllicable?

I remember wrong it is UV light that reflects 
How I will test my laser, if it has an IR filter or not?

Hey pseudo, or anybody else.
Has anybody tested out Wicked Lasers for IR with this method?
Cause I am curious to see how much they leak. I know it has a IR(I can see it from looking in the barrel) But I am curious to how much exactly is being leaked. And while different ones will vary, its still good to have an estimate.

Wicked Lasers sell the old CNI one and well I believe RoadRunners Fusion only gives like 0.5mW of IR. I'm not sure if he has an CNI one though and I don't know the amount that leaks through but with the WL and DL stuff you can be pretty sure you won't stare into a lot of mW's of IR.
Anyhow, this is just one typical eBay listing that is just so stupid:
