Request full-text PDF. . The Abbe refractometer that determines the RI of a liquid based on the critical angle is the most widely used one. Unfortunately, the measurement range is limited to 1.3 .This kind of refractometer was designed by Ernst Abbe in 1869 as part of his work with Carl Zeiss, a German optical instrument maker. Abbe is also famed for the development of the numerical aperture formula for microscopes and for the prism which bears his name. Two such Abbe prisms are the key components of this refractometer.The explosive growth of laboratory work after WW 1 led a number of other companies to begin its manufacture as well, including Adam Hilgar and Stanley in Great Britain, and Spencer Lens Co., Bausch & Lomb, Gaertner, and Valentine in the U.
