Explore: Polariscopes

needed] The basic advantage of a circular polariscope over a plane polariscope is that in a circular polariscope setup we only get the isochromatics and

operate the polariscope, a gemologist may turn the polarizing lenses by hand to observe various characteristics about a gemstone. Polariscopes make use of

A polarimeter is a scientific instrument used to measure optical rotation: the angle of rotation caused by passing linearly polarized light through an
