Turn on the polarimeter and allow it to warm up for 30 minutes. Fill the polarimeter cell with a solvent that has a known specific rotation value. Place the cell in the polarimeter and adjust the polarimeter until the reading matches the known specific rotation value of the solvent. Repeat the process with the same solvent to ensure accuracy.As shown in Figures 6 and 7, Schematic of Full Stokes Imaging Polarimeter by Pezzaniti J L et al.
