pass-445nm Dichros

[Xer0]

Guys,

before the C@sio era we all were using RGB dichros in G-R-B order, green was the most visable, so losses were acceptable, violet came last. now with 445nm there is so much of blue that it's a pity wasting green and red before it...

Are there any good and cheap dichros allowing to use Blue in the first order, then Green and Red (or Red and Green) ?

They do exist, i've seen them in some online store, but i don't remember which one

It would be attractive these days to blend in a 445-532-6xx order to minimize the loss of red.

OLD thread but ....

FYI afaik the dichros from the c@sio PJs work well and the blue LDs are the first to pass thru two dichros- the second one passes blue and iirc passes red and blue.

These are quite large-not too hard to make one into three(or two) with a good glass cutter- if you want to get some PM me.
