Experiment Tutorial: Absorbance Absorbance Experiments Absorbance spectra are a measure of how much light is absorbed by a sample. For most samples, absorbance is linearly related to the concentration of the substance. The software calculates absorbance (Aλ) using the following equation: Aλ = - log10 ( Sλ - Dλ Rλ - Dλ ) where S is the sample intensity at wavelength λ, D is the dark intensity at wavelength λ, R is the reference intensity at wavelength λ.
Experiment Tutorial: Transmission Transmission Experiments Transmission is the percentage of energy passing through a system relative to the amount that passes through the reference. Transmission Mode is also used to show the portion of light reflected from a sample. Transmission and reflection measurements require the same mathematical calculations. The transmission is expressed as a percentage (%Tλ) relative to a standard substance (such as air).
Experiment Tutorial: Reflection Reflection Experiments Reflection is the return of radiation by a surface, without a change in wavelength. The reflection may be: " Specular, in which the angle of incidence is equal to the angle of reflection. " Diffuse, in which the angle of incidence is not equal to the angle of reflection. Every surface returns both specular and diffuse reflections. Some surfaces may return mostly specular reflection, others more diffuse reflection.
Experiment Tutorial: Relative Irradiance Relative Irradiance Experiments Irradiance is the amount of energy at each wavelength from a radiant sample. In relative terms, it is the fraction of energy from the sample compared to the energy collected from a lamp with a blackbody energy distribution, normalized to 1 at the energy maximum.
