Enter the Cheap 445nm Diodes

(1/4) > >>

cfavreau:
There is a group buy on PL for 445 nm diodes pulled from a Casio XJ-A130


I ordered 1 diode and as soon as I get it up and running I will post some pictures and such.


Link to a post on Laser Freak in German on the matter:

They are selling for around ~$60 USD apiece.  I don't think they know the exact specs yet but they have been run over 100 mW and some at 470 mW (not sure the longevity...).   


Here is the post on PL:

Don't shoot me for posting a link... please...


Cheap Blue for Everyone!

drlava:
Here are a few more beamshots of a basic '400mW' module, no correction:






it does get a decent beam, 3x3mm at 3 ft. <2.5mrad

BlinkenLights:
OMG im SOOOOOo getting one

James:
That is outstanding!

This changes everything!

Now it looks like we have some quantum values to deal with.

We've got the low end at 658nm in the form of two DVD burning diodes and a PBS cube. That can put out about 400mW.

Greenie pointers can be had that supposedly do 180mW or better at 532nm.

Now we have true blue at 445nm doing about 400mW. I would assue that these things combine the same way reds and BluRays do, so that could be more like 800mW, if necessary.

So now it looks like the limiting factor is the power of the red.

Aren't there some BluRay diodes out there now that can do 200mW? So it would be possible to add like 400mW at 405nm. Do you think you would even be able to see it when with the 445nm in the mix?

Now I want to build an RGBV !!! ;D

James.  :)

drlava:
I don't think there would be any benefit of adding 405nm to this color.  But that decision is ultimately up to you. 
Oh and although I posted in this thread, this is one of the $475 diodes. :O
