Half-silvered mirrors and transmission and reflection

    "Half-silvered mirrors" and transmission and reflection

    I am curious about any equations (whether empirical or no) that can predict the thickness of metal (on a glass substrate) needed for a given transmission/reflection ratio. Gold, aluminum or silver, it doesn't truly matter. This should likely be a function of frequency, especially factoring in the substrate reflections.

    A pointer to a good text that can explain such a situation would be greatly appreciated if it's too bothersome to write in a reply.

    Thanks for any help,
