More info

Depending on the model, offer a measurement range 1.33 to 1.83 nD, or 1.33 to 1.81 it nD. The two have prisms of optical glass with a resolution of 0.01 na.With a weight of only 400 grams, refractometer for gemstones are light and manageable. The network connection allows the automatic switching between 110 and 220 V. refractometer for gemstones of Krüss have a cast aluminum housing and are supplied with a polarization filter and a manual.
To assess and monitor the quality of the precious stones, is commonly used a refractometer. This measures the refractive index (RI) and birefringence by means of driving of a beam of light through the stone, which is refracted at a defined angle constant. The index of refraction is an important parameter for the classification of minerals and precious stones.Each mineral has an index of refraction specific due to its chemical composition. With the help of a refractometer, this value can be measured easily and accurately. The structure of a stone may be crystalline or non-crystalline. Gemstones with a high refractive index tend to be very bright; for example, a diamond has a RI of 2.4; while the quartz is approx. 1,55.
