Transmittance

Transmittance is light incident on a sample that transmits through it. If the sample has low scatter (as with a clean, dilute solution), almost all the light not absorbed will be transmitted.

Advantages of Transmittance

Can be used to characterize effectiveness of samples such as optical coatings, window tinting and plastic tubing
Simple configuration. Setups can be assembled using virtually the same components as for absorbance measurements
Multiple sampling options. Choose from transmission dip probes, filter and lens holder assemblies, and other fixtures
