Refractive Index (Matching) Liquids
Also see our Specialized Optical Coupling Liquids
Cargille Refractive Index Liquids have become standard items in many laboratories as their applications have expanded from routine mineralogical identifications and quality control. New and
broader uses in many more fields such as chemicals, engineering, medical, forensic, optics, instrumentation are continuously discovered. Many special requirements for specific applications have
created a need for more technical data, new formulations, extended ranges, smaller increments and higher degrees of precision.
Since 1942, Cargille Laboratories, Inc. has been filling this growing need. And today, the largest and most comprehensive assemblage of refractive index liquids - over 250 stocked items -
are available for science, industry, medicine and education. For specialized and unusual applications, many more can be formulated and others are routinely researched in anticipation of new
needs.
Chlorofluorocarbon (CFC) components used in some Cargille optical liquids have physical properties that are harmless to the ozone layer, unlike those found in refrigerant gases, propellants and solvents, which are destructive. The components used by Cargille Laboratories have vapor densities ten times that of air, are relatively nonvolatile, and have boiling points at least 100°C higher than the highest-boiling CFC of those listed for removal from commercial use by the Montreal Protocol.
Applications
Cargille Refractive Index Liquids have a broad range of applications in diversified fields. The following table briefly illustrates some of the typical areas of use.
