Contacted them again and they said the real output is 2-5mw 473nm.

I bumped my bid cause it seems other people want it too.

That's a bit more like it. Hope you get it man. I really doubt it but if you get it and it turns out to be 473 then make a post:D

Maybe they have no idea what 473 is actually worth?:thinking:

Maybe they came across something like this and decided to resell it without knowledge of the value.

Not really that cheap considering the Dragon Lasers 30mW 589nm spartan is cheaper at $359 and their 5mW Aurora is even cheaper at $299 plus shipping.
Unless of course they had the price wrong and since raised it to the current $388 that link brings up.
Dragonlasers shipping to the US seems to be $26 which brings the totals to $385 and $325 shipped respectively for a known quality laser with a real company behind it.

Also, has anyone taken a look at this, or know how it works?

He should ask them for a usage fee! :crackup:

And haven't used one of those, but it uses a mirrored cone to form the circle, with the spot from the laser aligned with the tip of the cone. There was talk on PL a long time ago of using the same/similar optic to do the reverse and combine multiple beams into one. I think it ended up being not all that practical. There's a few interesting things you can do with those optics, and other similar optics such as Axicon lenses.

I was going to explain the optic, but diachi beat me to it. I'll bet they used styro's photo without compensation, but at least it's 15 minutes of fame.

Needs 5V IIRC, can't remember the pinout of the power/control connector, will try and dig it up...

Don't expect a nice beam, all of the ones I've seen were designed to be fiber coupled and as such didn't have collimation optics on the output.

Edit: Found it! :D

Pin Function
----------------------------------------------------------------------
1 GND
2 GND
3 TTL Modulation/Enable. Float/high is on.
4 +5 VDC
5 +5 VDC
6 Interlock, jumpered to 7.
7 Interlock, jumpered to 6.
8 Analog Modulation.
9 NC

You can leave pin 3 disconnected and jump pin 8 to pin 4 or 5. Pretty straight forward.

More info: http://www.repairfaq.org/sam/laserscl.htm#sclbwt1

That's for the 532 model, driver is the same though.
