Light Transfer (Light Transmittance)

  1. Oct 4, 2010 #1
    Can anyone please direct me to the formulation for calculating the amount of light transferred through a glass?
    Or the amount of light absorbed.

    Thank you

    May be you are searching for Lambert-Beer law.

    I had a look at the Lambert-Beer Law, but the text states that: The Lambert-Beer Law is valid only for diluted solutions.
    I don't think glass lies in this category.
    Any idea?

    No, Lambert-Beer (LM) law is valid.
    For example: one can apply to absorption of gamma rays in lead (for shielding calculations)
    And in X-ray absorption spectroscopy LM is often used.
    Also for finding attenuation of light in sun glasses, LM is used.
    Hope this helps.
