Zeeman Effect Apparatus with Electromagnet Advanced Physics Experiment

This CCD-based Zeeman Effect experiment system is designed to investigate the interaction between atomic spectral lines and strong magnetic fields. It enables students to generate high magnetic fields, observe Zeeman splitting and polarization states, adjust a Fabry-Perot etalon, and analyze spectral images using a high-resolution CMOS camera. The integrated image processing software provides real-time analysis for accurate measurement of spectral line splitting and calculation of the charge-to-mass ratio (e/m). Manufactured by Atico Export India.
