Polarimeters measure the optical activity of a substance. This is done by passing polarized light through a substance and observing the angle of light emitted. Optically active substances will rotate the polarized light while non-optically active substances will have an angle of 0°. This technique was developed to identify and study enantiomers which share many chemical properties typically used to distinguish one molecule from another, but that can have significant effects in chemistry experiments, pharmaceuticals, and food quality. While the original polarimeters required manual adjustments to obtain a reading, today's digital polarimeters perform readings automatically and give instantaneous results.

Description | The AUTOPOL I is Rudolph's most economical automatic polarimeter designed for education and less demanding applications where the budget is critical, but quality is still important.
Quality Rudolph manufactures its entry-level polarimeter with the same high quality optics as its more expensive The AUTOPOL I is Rudolph's most economical automatic polarimeter designed for education and less demanding applications where the budget is critical, but quality is still important.
Quality Rudolph manufactures its entry-level polarimeter with the same high quality optics as its more expensive instruments. While other manufacturers in this price range use Polaroid Plastic Dichroic Sheet Polarizers, Rudolph does not. Instead, Rudolph uses the same high quality Glan Thompson Calcite Polarizers used in its high accuracy models.Why are high quality polarizing prisms important? Because prisms are two of the most critical optical components in the polarimeter. Polaroid prisms are made of a polymeric plastic where the molecules are stretched and oriented in a specific direction so as to linearly polarize light. These types of plastic sheet polarizers are very inexpensive and are vulnerable to heat, warp over time, deteriorate from moisture, and also have greater light absorption than Calcite Polarizers. In many cases, the plastic polarizers must be replaced in 3 - 5 years. Glan Thompson Calcite Polarizers are comprised of a carbon crystalline structure similar to diamond and have excellent light transmission characteristics. The quality of these prisms is so good, Rudolph guarantees its prisms over the life of the polarimeter.
Temperature The Autopol I comes with a Temperature Probe so that sample temperature can be displayed and printed. However, if your product requires Temperature Control, then the Autopol I will most likely not be accurate enough for this type of sample, as is the case for 98% of pharmaceutical applications where a Certificate of Analysis must be issued....
