Cheap rip off or an actual 50mW 473nm laser for 30 bucks?

Well I want to see if it is 473nm ebay or any other website will say it's 405nm plus it claims it has a power of 50mW so it doesn't matter on wealth of knowledge what matters is that these companies correct themselves besides it's very cheap.

Yes there are hundreds of companies all over the web who have very wrong specs listed about their lasers. It is VERY obvious to many members here which ones are wrong and which ones are correct. Night and day. I am telling you it is not 473nm. It just isn't. I wish they would correct themselves. I really do. I have sent numerous emails to focalprice, dealextreme and all kinds of other websites including ebay sellers telling them about the errors in their listings but very rarely do they change them. I understand that it is very "cheap" it just really bothers me that these companies continue to prey on the naive. What bothers me even more is when a member like yourself who seems to genuinely be interested in lasers and wants to learn more about them spits in the face of those who have come before you and voluntarily hand your money over to these scammers. You are no longer the naive being duped. Just foolish.

Its too bad this happens all the time, i'm sure this is just another phr-like bluray, or even worse.

As mentioned, bluray makes many materials fluoresce, and the spot on a piece of paper can look convincingly blue, as if it were 473 nm or thereabout. A seller could just post a completely undoctored picture of the dot on paper with the listing and convince people its actually a blue laser - with or without knowing what he's doing.

If anyone ordered it and gets a bluray, file a complaint/dispute with paypal, perhaps that'll teach them to stop these tricks.

It IS a 405nm blu ray laser. The laser is PURPLE, and you will see many misleading pictures all over Chinese websites that look identical to this. They're always shining it at the same material inside the box that the laser comes in, which fluoresces to a blue color. I'll take a picture with my blu ray laser right now for you...

These are taken with my Cell phone camera so I couldn't get the dot any smaller, but it still allowed me to adjust the ISO lower

I already knew this my 50mW blu ray does this and yes chinese companies do post the same pics and sometimes it's not even of the same laser! (Ebay does this a lot.)

It was a joke, sorta... The light source is stored in the EXIF data, you can choose white balance on the camera from "daylight", or "incandescent" or "fluorescent", or "nighttime" etc... I just thought it was funny that the only source of light in those photos is *fluorescence*, so it's appropriate that it says "fluorescent" under light source.

Never mind... Geeky joke observation, probably not funny.

Well actually believe it or not the laser came today (I have no way to take pics) I was surprised I thought this would take weeks. This is a NewWish brand laser. The wavelength is 405nm and it seems to be about 20-30mW. The label does not even claim it's 473nm it says 405nm. the output claims to be <50mW. The output is a little weird one second it will be at a good 30mW then it will decrease for a minute then increase again. The dot stays in a clean TEM00, but I find this a strange because this thing overheats in about 5 mins of use. This laser looks like the kind of NewWish lasers ebay has.
