Refractive index ernst abbe
WebMay 27, 2015 · In optics, the Abbe Value is a measure of the degree to which light is dispersed when entering a lens, with high numbers indicating low dispersion or low chromatic aberration. It is named after the German physicist Ernst Abbe who defined it. Basically, the Abbe Value refers to the clarity of transparent materials. When looking … WebThe most common type of refractometer, developed by Ernst Abbe in the late 19 th century, is based on measuring the critical angle of total internal reflection at an interface between the investigated material and a reference prism with a known higher refractive index.
