Has somebody pics of an 80mW 532nm?

Pictures don't say much, I doubt anyone will be able to guess which power this laser is:

There is nothing added to the air, no for or anything to visualise the beam more than normal scattering and dust.

^ According to the luminosity of the other lights on the pic I´m sure that you used a long exposure time. My guess is that it has less than 10mW.

The exposure isn't that long because the picture would be much lighter with the other light sources available. I'd have to agree with regalis. ~50mW

Based on the 30 second exposure as noted in EXIF data (cheating :p) I'd say it's probably a 543.5nm HeNe beamshot (1-2mW?).

Certainly proves the point that beamshots can be misleading. :D

@Bluefan

Considering there is some light in the room... curtains... and there is clearly visible specle, I'm gonna go with ~150mW.

I did the same thing. I will also say 2mW max

Back on topic... Here is what a 130mW pen looks like with nothing more than a single burnt match in a lit room:



Here is 530-540mW with no smoke:


And here are a few lasers outside to show what powers look like what with no added effects.



From left to right: 130mW - 400mW - 500mW - 540mW

Hope it helps

It's a super cheap 532nm pointer. I measured the green and it's between 0.5 and 0.6mW, depending how warm it is. Funny how people estimate it at 50 or even 150mW, 100 or even 300 times more. It was getting dark outside and the room was very dark. The laptop had it's screen at minimum brightness.
The funny thing of the picture is that the room looks very normal and lit from outside, but only after 30 seconds of exposure that very little light looks like normal daylight.

Here's one where it hit a light instead of dark material:

Moral of the story: don't trust pictures (unless the exif data reveals all).

Pictures mean nothing what so even because you have no idea what is in the air or the exposure or the cameras own color pickup traits or if they have been edited. If you want to know what 80mW looks like in your air in your house you gotta buy one and find out.

Very true, however I think it's safe to say that if a seller on here used pictures like that, he would be run off in short order.

Nice pic... and great post. +Rep.

I'm going to use it next time someone asks me for a beamshot:p
