Why do polarizers only work within a certain range?

    hi there

    I think you are going to have to elaborate a bit more

    particularly where you got an idea of minimum and maximum wavelengths
    references ??

    what sort of polarisers ? sun glasses type ?, camera type?, scientific use ones ?

    The polariser I use on my camera works well across the full visible spectrum
    maybe further each way, I have no idea
