Fluorescence and Stokes shift

Objectives:

Using the side port of the sampling unit the Stokes shift of fluorescent compounds in solution can be
measured.

Procedure:

1. Using an open bench set up and a UV lamp you can detect fluorescence by pointing the fiber at the

side of the cuvette.

2. Visible fluorescence of fluorescein from UV excitation by a UV led can be measured. This

phenomenon is used by opticians to show up scratches on the cornea and is the basis of confocal
microscopy used to view biological samples.
