Refractive Index Fluids
The standard group of Cargille Refractive Index Liquids consists of a total of 220 different liquids divided into six different series extending in the range from 1.300 to 1.800. The Certified Series cover the range of the most minerals, most chemicals, and practically all biological materials.
Series AAA: Range 1.300 to 1.395 RI, 20 different liquids
Series AA: Range: 1.400 to 1.458 RI, 30 different liquids
Series A: Range: 1.460 to 1.640 RI, 91 different liquids
Series B: Range: 1.642-1.700 RI, 30 different liquids
Series M Range: 1.705-1.800 RI, 20 different liquids
Series E Range (High Dispersion): 1.500-1.640 RI, 29 different liquids
All refractive index values were taken at the "D" line which is 589.3 nm (5893Å) at 25° C.
