It's mislabelled IIRC, it's 445nm.

Great price for what it is IMO, others here have bought them and they like them.

I recently picked one up and the 473nm is definitely mislabeled. Its a 445 from what I can tell. Very nice and small.

The insides

Worth it I think.

Thanks for the heads up! Sucks though because I was really hoping for 473.
Either way, Blue+green is somewhat like a cyan in itself I would guess. I'm going to buy one, it will be be my first real laser! (non-pointer)

Polonium do you have any more pics or videos? I would very much like to see them.
Also, what do you use for power, any adapters or a particular batteries you recommend?
Would it be possible to travel with this, with a smallish 12v battery? Seems like it could be fun!

Thanks

Do you have any white beamshots? It would be nice to see the natural color balance of the unit, divergence, alignment, beam diameters etc.

I'm interested too, I heard it's not easy to get a bright white color :p lots of careful color mixing

To my eye the dot is very balanced. I have yet to be able to take a good picture with my point and shoot. My good camera is packed deep away in boxes somewhere :(

I will try and make a video on my point and shoot and post back here.

Also it does LPM right on spec @ 200mW:D

Still is 88$ +24$ to ship no break on combined ship- SHE wants 240$ usd to ship 10.. she was 'called out' and yet still leaves the 473 there- poor way to do biz IMHO- other complaints have been posted here as well.
I would rather pay more to Techhood- he ships super fast too.

thumbs down on laserland

Yeah, give your business a more reputable eBay seller like Techhood -- not to one like Laserlands who doesn't use his/her brain and directly quotes the erroneous specs of the OEM. YES, WE DO KNOW BETTER THAN YOU LASERLANDS!

To Laserland's credit, he/she did refund Apocalypse his money for the mislabeled product. However, Laserlands didn't admit "wrongdoing" and even changed the listing to state "450/470nm" to cover all the bases (and then outright changed it back to 470nm as you can see in this thread's OP listing).

Buy that laser product at Techhood like Hakzaw1 mentioned. Not only is Techhood more reputable, but the RGB laser product is cheaper ($99 + $10 vs $88 + $24) and spec'ed at 300mW instead of 200mW. Get that one.

Ok, unfortunately I ordered this laser before Bionics advice. It arrived today in the mail. I ordered from ebay user laserlands, the link I posted above.

The item looks very used and has many scratches and dings on the case. After ~15 min of use the red diode barely lights up. Strange.
VERY disappointing! Was fun while it lasted though.

I am asking laserlands what they want to do to fix this problem. Hopefully we can get it straightened out.

I bought one of these (from LL) and I'm pretty happy with it. The blue is a PL450 and the beam alignment is pretty good, especially considering the package was pretty much crushed when it arrived. Collimation is also decent; 1/2" dot @ 50'. I plan on building some variant of a WFTM with it. My only real complaint is stability. After ~15 minutes warmup time the beam becomes noticably greener. From what I've been reading about the PL450 though I should be able to dial up the power on this quite a bit and tweak the red and blue to compensate for the extra green I'm getting when the thing warms up.

How do you make adjustments to the power? That would indeed be very interesting.

It has separate pots for tweaking the output of each laser. It also has TTL blanking inputs but I plan on doing a little soldering to get full analog control of each color.

Where are the pots located and are they hard to get to?
What are the red/green/blue inputs in the opposite side of the board for? Just got this thing today. :eek:
Can you please go into more detail on how you could make it completely analog for full color control? :) Thanks

If they don't start selling these with analogue modulation then its pretty much useless for a projector. I mean, come on! They have been around for a while now!
