Product Information
Sodium filter for Kruss Professional Model ER601 Refractometer. The sodium filter is used to produce monochromatic light. A monochromatic yellow light source is the standard for measuring gemological refractive indices.

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.
