Experiment to Demonstrate Normal Zeeman Effect
This experiment involves observing the splitting of the red cadmium line perpendicular in transverse configuration or parallel in longitudinal configuration to an external magnetic field. The observation in longitudinal configuration is made possible by a stepped hole on the pole piece of the electromagnet. As the light from the Cd lamp passes through the Fabry-Pérot etalon, interference rings are formed which, like the spectral line, split into doublets or triplets depending on the direction of the external magnetic field.
The splitting of the interference rings is recorded using the MikroCam SP 3.1 microscope camera. A red filter applied to the focusing lens of the dedicated digital camera increases the contrast/depth of field for analysis of the Cd lines.The associated software (for Windows) allows both qualitative observation of the live image and quantitative analysis using screenshots and videos. The occurrence of linear or circular polarization is analyzed using the polarization filter or the quarter wavelength plate with polarization attachment. The whole experiment is built on a stable optical precision bench system.
