• 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.
• Rudolph manufactures its least expensive polarimeter with the same high quality optics as its more expensive instruments. While other manufacturers in this price range use Polaroid Plastic Diachronic Sheet Polarizers, Rudolph does not. Instead Rudolph uses the same high quality Glan Thompson Calcite Polarizers used in its high accuracymodels.
• Why are high quality polarizing prisms important? Because prisms are 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, can 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 transmissioncharacteristics. The quality of these prisms is so good, Rudolph guarantees its prisms over the life of the polarimeter.
