Polarimeter

The Polarimeter is a precision optical instrument designed to measure the angle of rotation of plane-polarized light passing through optically active substances. Essential for quality control in pharmaceuticals, food science, and chemical industries, our export-grade polarimeters combine ISO-compliant accuracy, robust construction, and user-centric automation to meet global laboratory standards.

Product Details

Polarimeters operate on the optical rotation phenomenon: A monochromatic light source (e.g., 589nm sodium D-line) is polarized through a Nicol prism. When this polarized light passes through a chiral compound (e.g., sugars, amino acids), its plane rotates proportionally to the substance’s concentration and molecular structure. A precision analytical rotary scale or digital detector quantifies this rotation (±0.01° resolution).
