Polarimeter, which is known as an optical rotation meter, is an instrument to measure optical rotation of "optically active matter" such as saccharin, ascorbic acid and sodium glutamate.

Long Lasting LED

"LED" which has a long life and lights overwhelmingly fast in comparison with a sodium lamp is used as a light source. The wavelength of 589nm equivalent to D-line of the sodium is ensured by using interference filter together with "LED". 

Digital Display

Look through the eyepiece and match the brightness at the left and right of the visual field with push-button switches. Measurement value is 

Smooth Measurements

Push button switches are used to the rotate the analyser. In addition to the right (+) and left (-) switches , the POLAX-2L has the shift/temp switch with which the rotation speed can changed in two steps.

Applications

  • International sugar scale (°Z) is used for sugar measurement and polarimeter is essential instruments for this procedure
  • Many optically active materials used in food additives , flavouring and perfumes, the polarimetric analysis is widely applied.  
  • Polarimeter is widely used for educational purposes in the field of "Physics" and "Applied Science" course for understanding polarized light, optical rotation, optical active substances and optical activity.
