  • This section provides a background to infrared light [1] and its location relative to visible and ultraviolet light in the electromagnetic spectrum [2].

  • The Beer-Lambert Law [3] is a linear relationship between the absorbance of light and the properties of the material through which the light is travelling.

  • Light absorbance can easily be calculated from % transmittance [4] data using the equation or calculator provided.

  • Visual demonstration of near infrared technology.
                - Near infrared absorbing filter [5]
                - Visible opaque infrared transmitting filter [6]
