Sodium Filter For Kruss Professional Refractometer Model ER601
Gemstsone refractometers are used for observing the refractive index of a gemstone or mineral. The refractive index is an important parameter in identifying a mineral or gemstone. While it is possible to get a reading using a white light source a monochromatic yellow light source is the standard for all gemological refractive indices. The sodium filter is used to produce monochromatic light. For best results it is recommended that either a sodium filter or sodium light source be used with a refractometer.
