Multi wavelength Abbe refractometer

(1100nm max.), the refractive index (nd) and Abbe value can be measured with different wavelengths in the wavelength range of 450 to 1100nm（ ν d/ ν e）。

The measurement results are determined by adjusting the dividing line to the cross point. The measurement results are displayed in digital form on the LCD screen. Compared with the traditional Abbe refractometer, the reading is faster and clearer.

It is especially suitable for high-precision measurement of refractive index of polyester materials such as spectacle lens, film, film and liquid crystal.
