447nm diodes + small question regarding combining

[masterpj]

My red is almost finished and aside from showmaking my interest in building projectors and the likes has grown and grown.
I have aquired a lot more knowledge when it comes to diode types and their wavelengths and their setbacks and so forth (partually thanks to some PL members around here: Swamidog and astatic to name a few).

I myself think the 445nm diodes are cool because of their huge amount of power and low cost but am more fond of my 473nm blue because of its color *sadly not of its modulation because its DPSS after all*.

However I recently started hearing about the 447nm diodes (call me slow)
I rarely hear talks about 447nm diodes.

Does anyone have more information about these of which I can read up? Where are they being sold?

Another small question is how I would combine 405nm and 445nm or 447nm alongside with my 473nm module (So violet, light blue and darker blue)?
So far my solution to combining these wavelengths would be a PBS cube....however that would only allow me to combine 2 wavelengths and not 3.
I don't believe there exists dichro's with a really narrow range or do there?

Edit: my other thought would be: to knife edge the 405 and 447nm together and then combine these 2 with the 473nm module through a pbs.

We had dichroic for combine 405nm+473nm, but can't working with 445nm.

Can u guys still get these?
Does it let through 405nm?

it is reflect 405nm pass 473nm

the 445 and the 447 diodes are the same diode. even if they weren't, that 2nm spread would be all but unnoticeable. not at all worth the money, time, and projector space.

Sweet! thanks for the headsup. That explains a lot why it's mostly unmentioned.
405+445+473 it is .

@Bridge if you still have these dichros or know a place to obtain them, please let me know through PM or something.
I'm interested.

Yes, we had, PM send.
