The Polarimeter can be used to measure chiral properties of optically active samples without chemically modifying or destroying the sample. This is a vertical polarimeter that uses a 589 nm LED, a fixed polarizer, and a manually rotated polarizer to detect changes in rotation of plane-polarized light in the presence of an optically active compound. Used with Vernier technology, students no longer have to determine the optical maximum with their eye but have a graph that shows a clear change in the light’s polarization.
