    Hi folks,
    So I'm building a Schlieren system in work and it's going pretty well. Here are some of the first images:

    Anyway my current set up uses a razor blade to block some of the refracted light resulting in what you see above. I would like to replace this with a colour grad filter like this image:

    This will allow me to quantify the amount of refraction and therefore the temperature. However I cannot find such a filter anywhere online.
    So I guess I'm going to have to try to print one out on transparency.

    Does anyone know anywhere that does custom filters like this? Or somewhere I could get this printed on glass?
