Abbe laboratory

An Abbe or laboratory refractometer is a bench-top refractometer that offer the highest precision of the different types of refractometer, They are still used today as an inexpensive alternative to digital laboratory refractometers.

They are also possibly the easiest method to find the refractive index of solid samples, such as glass, plastics, and polymer films. Some Abbe refractometers utilize a digital display for the measurement, to eliminate the need for discerning between small graduations. The user still has to adjust the view to obtain the reading, however.

Atago Multirange Abbe refractometers have the capability to read at wavelengths other than the standard 589 nanometers these instruments utilize special filters of the desired wavelength of light, well into the near infrared, and can be used determine a sample's Abbe number.
