The emerging polarized light then passes through the glass-half of the half-shade lens and emerges unchanged. As it passes through the quartz-half, however, it is rotated by 2θ and emerges at an angle of 85º.

Together, the Laurent polarimeter with a half-shade plate allows for more accurate determination of optical rotation in substances. This is particularly important in fields such as chemistry and biochemistry for studying the properties of chiral compounds. Popular Articles.The Lippich polarimeter is a more accurate variant. An improved method, based on an intervention of the Austrian physicist Ferdinand Franz Lippich in the late 19 th century, uses an additional optical element which introduces some rotation of the polarization direction for about half of the beam area after the polarizer. One can then not obtain .
