Quality Components – Sugar Polarimeter
Rudolph manufactures its entry-level automatic 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 (Figure A).
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 ($50.00 USD) 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 sugar polarimeter.
Polarimeter Sample Temperature
As shown in Figure B, the Autopol I comes with a Temperature Probe so that sample temperature can be displayed and printed. However, If you need to control temperature, The Autopol I-T, should be selected as this has Rudolph’s Patented and exclusive TempTrol® Temperature Control System.
Optional Accessories
The Autopol® I is a Single Wavelength Instrument operating at 589nm. The 589nm wavelength is often referred to as the Sodium D-Line. The Autopol® I includes a 100mm or 200mm glass sample cell. A full range of optional sugar Polarimeter accessories are available as shown in Figure C.
