A way to improve the beam characteristics of multi-die emitters?

[taschenlampe]

I wonder if some kind of beveling/faceting of the dome of multi-die emitters would
help to get rid of the doughnuts and beam irregularities which are obvious if they are
used with SMO reflectors - WITHOUT loosing the throw capabilities of the SMO
reflectors.

The dome should look like diamond with very small facets.

The idea behind – if I can't see the cross between the dies because of the facets –
also a reflector or optic should not be able to see/reflect/project it.

Just a thought …

Well, the P7 dies are pretty far apart. Moving them closer and filling the gap with phosphor would do the job as well.

I think that optics will work better with multidie LEDs. I've ordered some Sekonix optics for P7 so I'll see next week

i am wondering how closed together Cree MC-E dies are...

I optics do work better, however, sometimes the geometry of the optic just causes the die of the LED to be projected out in the beam, but with the newer optics I have seen, they can do really well with blending the light beam and making it even (some companies just use diffusion filters (surefire does on most of their newer models)).
