Manual and automatic digital polarimeter

Polarimeters are optical instruments utilizing so called polarized light. There are a great number of organic and inorganic substances being “optically active” in their liquid or dissolved state.

Such substances are able to 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.

Polarimeter for laboratory and industry 

The measured angle of rotation depends on the nature of the sample (“specific rotation”), the concentration of the optical active components, wavelength of the light, sample temperature and optical path length. SCHMIDT + HAENSCH, founded in 1864, offers a variety of polarimeter models based on decades of experience. The modular concept allows each customer to compile a custom-configured polarimeter including accessories.
