How to roughly estimate the beam power of a 532 nm laser?

[VioletGiraffe]

Thanks. It says 5mW, though?.. And, of course, does not ship to my country.

Yes, I noticed they don't ship to your country after you posted, but there are others that will.
You can't believe the 5mW claim, it will generally be higher.

Really? I would expect them to be below spec, not above. Why would they underrate them? For legal reasons?

Here's another ebay seller that ships to Ukraine -link- $3.99 +$2.99 shipping.
Yes, they state less than 5mW for legal reasons, this allows them to list lasers on ebay.

Thanks a lot! Is it safe to assume that all lots consisting of 3 lasers that look like these are indeed the very same models?

 

[BowtieGuy]

Personally I wouldn't assume anything with these sites, also, I'll bet that the "blue-violet" laser in this package is a 405nm violet laser, and not a 445~450nm blue laser.

Great find, Jeff. Yeah, don't assume anything when it comes these cheap Chinese lasers.

eBay does not allow listings of Laser Pointers
more powerful than 5mW... That is why any
Laser Pointers on eBay are stated at 5mW.

Like it was noted earlier... The only way to
know the power of any Laser you may have
is to test it on a Calibrated Laser Power Meter.

I don't think of buying a laser power meter as money gone- good ones used gently re-sell easily..
When members decide to move on from lasers their LMPs sell first if the price is decent.
.. not to be nosey --but what is your inspiration for your username??

VG, PM me your phone number, I'd like to talk to you about lasers in Ukraine.
