WTB: Combine 642/660nm Dichro

[flecom]

anyone have one of these from the group buy?

I would really like to get one before SELEM

PM me if you've got one you wouldn't mind parting with

Sorry, can't sell you one as it's being used in my projector .

However, just a 'heads up' that you *really* need to be super accurate when aligning the dichro. Half a degree or so in either direction is enough to introduce huge losses. Hit the 'sweet spot' though and everything's hunky dory.

I reckon there must be quite a few of these knocking about that never made it into projectors. However, I have to say that I think the combination of 642/660 is stunning and certainly adds something to the colour gamut.

Cheers

yep I have read the horror stories, but I've got a lot of 660 and 642 that are begging to be combined before SELEM... someone must have one of these kicking around?

Don;t most people do it with a PBS?

thats great if your combining two single diodes... my 642 and my 660 are already cross-polarized so PBS wont work

I've got two leads... lets see...

if not I am going to have to suck it up and order one from Semrock (ouch!)
