Confirmed - Osram PLT4 - A "new blue" wavelength :)

You also have the problem that different wavelengths refract differently through the same lensing.. As rhd demonstrated with the diffraction grating. It would be hard to focus and multiple wavelengths the same amount with the same lens.

Chromatic abberation can be fixed (mostly) with a pair of lenses (achromatic doublet). As mentioned, I'd be more worried about the different emitter locations.

Wonderfull !
that's a perfect diode for a blue keychain laser.
i want it in this host:

Are you going to put a 200 dollar diode in a keychain host haha

 

[qumefox]

Well the reds and blues are usable, so that would only be a $100 diode. heh.

i hope so
