443nm

... a kind of suspense thrilling story ...

Thats very nice, Dave! How does it compair in apparent brightness to 473nm?

IT looks beautiful in top picture, almost like you've put a solid blue perspex bar across. Certainly doesn't look like light.

Nice colour as well, maybe a little light for some tastes but nice never the same.

It's a direct injection blue diode - just like the 445 nm Nichia diodes. (The one's you see in those lovely Arctos projectors!)

They're small because they don't have a Vanadate crystal or a BiBO doubling crystal (or any of the associated optics) or a pair of TEC's like a 473 nm DPSS laser does.

On the other hand, I'm sure they're every bit as expensive as the Nichia diodes, which means they're *way* out of my price range...

Still, I gotta admit that it's fookin' beautiful!

I really want to get everything mounted properly and mixed with red and green to find out :) Those pics were taken with a bit of haze in the room..

Please? And a supplier? :D

It all looks good but don't forget about ratio. 443nm is the same as 660nm You need minimum a power of 4 to balance it.

yeah dave, how much are they ?

and the Price is ..... " Dave will be right back after the commercial break "



doh..... :D

all the best ... Karl
