The S+H VISPOL-Series Manual Polarimeters feature full circular scales of ±180°. With the use of the Vernier scale, rotations can be measured to an accuracy of 0.1° (an experienced user can potentially achieve accuracy of 0.05°). The rugged design allows for heavy use at the instructional level.

Measurements are made by rotating the Vernier scale disc with the coarse/fine controls; which, in turn, adjusts the analyzer. The large diameter of the Vernier scale disc allows for highly sensitive comparisons of half shadows resulting in accuracy typically not possible with manual polarimeters.

The optical assembly (Vernier scale disc, polarizer, analyzer, & sample compartment) is tilted 15° from horizontal. This results in more convenient and comfortable operation.

The polarizer is fitted with a thin, high-quality, 2-part quartz disc which produces the divided (2 half shadows) field of view. The half shadow angle is dependent on the light source used. With sodium light (λ=589nm) it’s 8°, and 9.5° for mercury light (λ=546nm). When the 2 half shadows are view during measurements, right-shadow shading indicates a dextrorotatory sample and left-side shading indicates a levorotatory sample.

Two types of light sources are available. Halogen lamp light sources coupled with interference filters are less expensive. Due to the longer life of halogen lamps and instant operation, this style is the preferred choice for instructional and general testing. A sodium arc lamp light source is also available for absolute accuracy.

A wide selection of S+H samples cells and quartz control plates are also available.
