Polarimeters, Manual, with LED, Halogen or Sodium Arc Light Sources
Overview
The German manufactured S+H VISPOL-Series and the VEE GEE Model C25L 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, in turn, adjusting 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 and sample compartment) is tilted 15° from horizontal, resulting 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. When the 2 half shadows are in view during measurements, right-shadow shading indicates a dextrorotatory sample and left-side shading indicates a levorotatory sample. The half shadow angle is dependent on the light source used (with sodium light (589nm) it is 8°, and with mercury light (546nm) it is 9.5°).
Three types of light sources are available. The cost effective Model C25L features a long-life, energy-efficient LED light source with a 589nm filter and instant operation. An S+H VISPOL Series polarimeter with sodium arc lamp light (589nm) source is available for absolute accuracy. The S+H VISPOL Series with halogen lamp light sources coupled with interference filters (589nm sodium mimic or 546nm mercury mimic) are less expensive, the halogen lights have longer life and operation is immediate. This style is the preferred choice for general testing.
A wide selection of S+H samples cells and quartz control plates are also available.
Features of the S+H VISPOL Series and the C25L Manual Polarimeters:
Rugged design and simple operation
Wide measurement range ff ± 180°
Potential accuracy up to ± 0.05° with experienced users, ± 0.1° is easily obtained
Sample cells up to a maximum of 200 mm
The economical C25L with long life LED light and interference filter is ideal for demanding instructional applications
The S+H VISPOL Series offers Halogen or Sodium Arc Light Sources, Sodium Arc is the choice for absolute accuracy, Halogen lamps with interference filters are more economical, have longer life and instant operation
