arent' all beamsplitters polarized?
Yes, that is what I want to do. I was trying to work out what would be cheaper. A waveplate and pbs, or using a npbs. Thanks Alaskan.
Oh, I asked the manufacturer whether it was possible and he stated it was. Just as well I didn't go through with it then.
And yes Alaskan got there first. :na:
Er... that is exactly the effect I was going for.
No i'd better stick with a waveplate and a pbs then.
