An Abbe refractometer is a laboratory device for measuring refractive index with high precision. The refractometer was developed by Ernst Abbe in 1869. It resembles a microscope and incorporates an illuminating prism and a refracting prism between which the specimen to be measured is sandwiched into a thin layer. By adjustment of the measurement knob, the line of total internal reflection (the boundary line between light and dark) is aligned with the cross hairs in the ocular field of view. The refractive index is then read from the accompanying vernier scale.
