Introduction

Compared with other important properties of light such as interference and diffraction, polarization is more abstract and relatively hard to understand. Without special equipment, human eyes or even optical detectors cannot recognize polarization phenomena. LEOI-42 is developed to help students understand the concept and mechanism of polarization. It allows students to measure different types of polarization and the working parameters of optical elements involved. The system is designed for manual operation in order to enhance students’ hands-on ability and consolidate their knowledge and skills. Experiment results can be graphed to schematically illustrate the theory of polarization. Students should acquire a fundamental understanding of polarization and the mechanism involved in polarization elements.

The instruction manual contains comprehensive materials including experimental configurations, principles and step-by-step instructions. Please click Experiment Theory and Contents to find more information about this apparatus.

Using this system, the following experiments can be conducted:

1. Verification of Malus's Law

2. Function study of a half-wave plate

3. Function study of a quarter-wave plate: circularly and elliptically polarized light

4. Measurement of Brewster's angle of a glass plate

5. Measurement of refractive index of a glass block

6. Observation of polarization rotation of light going through a glucose solution

7. Measurement of specific rotatory power of a glucose solution

8. Measurement of concentration of a glucose solution specimen
