LEOI-40 Experimental System for Polarized Light - Complete Model
Description
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-40 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.
