    Default Where to buy dispersive prism in the UK?

    I have been searching for a dispersive prism for a lumia projector. There are a few available on fleabay but most seem too big for what I want and the Thor labs prisms are a little more than I wanted to spend.

    Any ideas of where I can buy or maybe harvest one from a piece of everyday equipment?

    Thanks
    Keith

    Edmund Optics perhaps?

    Are you using gas? If not it is easier to just dichro shift them.

    Not UK, but prices and shipping rates are reasonable.

    No, using cheap and nasty diodes for this one. I imagine they won't be very well aligned in the first place. Would there be much difference in the light output using dichros compared to a prism?

    That is what I mean, just hit your effect with this beam. if they are not all perfect you will be pretty good. I only separate the beams on one effect for my whole rig. Most other are hit just strait white light, but not perfect converged.
