Polarimeter POL-1 
Polarimeter for simple laboratorial application / 3 x magnification / nicol prisms / measurement of concentration of chiral substances / tube up to 200 mm / 
monochrome light source / 589 nm wave length / open pitch circle of ±180° 

The polarimeter POL-1 is a robust device ideal for simple laboratorial applications, whether for education or for training. The polarimeter POL-1 is designed to measure the concentration of chiral substances (e.g. sugar) in solutions. Polarimetry is a method to analyze the purity of a solution and to determine its concentration of chiral substances, such as glucose, fructose, saccharine e.g. in the sugar industry, creamery, wine industry, beverage and fruit industry. The polarimeter POL-1 can also be applied in wine laboratories, or for the analysis of admixtures in food, in medicine to determine the amount of sugar and albumin in urine, in the cosmetics industry to test chiral essential oils and fragrances. The monochrome light source emits light of the Fraunhofer sodium-D-line with a 589 nm wave length. The polarimeter POL-1 has an open pitch circle of ±180° with a subdivision in integer angular degrees and consists of two Nicol prisms. The fixed polarizer polarizes light coming from the illuminant in a linear order. The rotatable analyzer that is placed behind the polarizer ensures defining the position of the polarization layer. The polarimeter POL-1 follows Laurent's half-shade method. It can hold tubes with a maximum length of 200 mm. The polarimeter is ideal to set foot in the field of polarimetry and gather initial experiences. If there are any questions about this polarimeter POL-1, please have a look at the technical specification below or call: UK customers +44(0) 23 809 870 30 / US customers +1-410-387-7703.. Our engineers and technicians will gladly advise you regarding the polarimeter or any other products in terms of regulation and control, or scales and balances of PCE Instruments.

Polarimeter POL-1

Due to two sequenced polarizers -  the second one is called analyzer - the following effects can be observed:

  • Analyzer is placed in same angle as polarizer: light can transmit and the polarization plane is preserved.

  • Analyzer is in a 90° angle to polarizer: light can not pass through, the field appears to be dark.

  • Polarizer and analyzer placed in a 90 ° angle again, a substance is applied, which changes the light polarization plane (so called chiral substance), so that the electronic field vector is rotated into a certain angle. The analyzer must be further rotated, in order to reach the dark spot again. The merit of this rotation is a characteristic constant (rotating angle), which is used for the analysis of the substance, in order to determine it, and its purity and concentration.

Nowadays there are many known chiral substances (either natural or synthesized) that are able to rotate the light polarization plane. 
Important examples are: 

  • Sugar (saccharine)
  • Some natural crystals, such as quartz, calc spar CaCO3, cinnabar, sodium chlorate
  • Liquid crystals for displays
  • Many chemical solutions that are chiral (i.e. they have two "mirror"-enantiomers) and play an important role in areas of medicine and food, e.g. ascorbic acid (vitamin C), Citalopram (anti-depressives)
