Hi all
I would like to get hold of a NON-Polarising 50/50 Beamsplitter Cube specifically coated for 532nm.
If anyone has one of these could you please get in touch with a price.
Thanks

Just a thought Jem but how about a Dicro set some way off it's optimum performance angle. I'm sure setting it at an certain angle you can get about 50/50 from a Dicro and they are not Polarised sensitive.

jem-
does it have to be a cube? i have a 50/50 splitter broadband coated. i can check the pass/reflect measurements if ya want specifically at 532.

This is for a specific holography setup and the geometry is very important. I have to have a beam passing straight through and the reflected beam exiting at exactly 90 degrees.
I could use a beamsplitter plate I guess (it has to be exactly 50/50 though), it's just that I have a nice adjustable mount for a cube and in this instance it will fit better into this particular setup.
Cheers

Can't you knife it with a std. fs mirror?

I think I've got one if you don't mind the shipping... I think it's a lambda... still new.

Maybe look at this too, If you haven't laready found something.

many have missed the boat on this topic - 50/50 for 532 @ EXACTLY 90 degrees...this is not a cheap optic. when you find it post the prices and picsI would NOT use a cube, I would use a 50/50 532 beam splitter

What's wrong with a cube? I though it was a standard.
