Bellow is a table of the index of refraction of a few liquids that may be useful index matching in an experiment. The measurement of the refractive index was measured using an ATAGO PAL-RI handheld refractometer. Uncertainties reflect measurement uncertainties and are not indications of batch to batch variations in these off the shelf products.
