Polarimeters

Polarimeters are optical instruments utilizing polarized light. There are a great number of organic and inorganic substances that are optically active in their liquid or dissolved state.
Such substances can rotate the direction of oscillation of polarized light around a determined angle. This angle of rotation is measured by a polarimeter with highest precision. Thus, a polarimeter will be used to determine the concentration of the optical active substance which is dissolved in an optically inactive liquid.
SciMed offers a comprehensive range of polarimeters from Schmidt and Haensch, a Berlin based company founded 1864. Schmidt and Haensch are at the forefront of development of polarimetric techniques and are responsible for many of the improvements in methods through innovative design solutions. The range of polarimeters provide a solution to every requirement from simple concentration calculations to comprehensive studies of a compound’s effect on properties.
