This projective ABBE instrument is designed for the measurement of refractive index(nD) and the average optical dispersion(NF-NC) of the transparent, the semitransparent and the solid matter (mostly transparent). It was connect with a circulating thermostatic bath, can measure the refractive index in 0℃~50℃.
Refractive index and the average optical dispersion are important constant among physical constants. They can indicate the optical property of purify rate, concentration and size of optical dispersion of materials.
It was widely used in oil industry, fat industry, pharmaceutical factories, paint, food processing, chemistry, sugar refineries, geologic etc., and relative factories, school and research center.
